wip: (incomplete) work in progress
doc: documentation changes
inf: informational only

v0.2.b15, 16-MAY-2010:

fix: correctly change the view menu's and game list tab's icons when the view is selected via the combo box under the game/machine list
fix: ROMAlyzer (cosmetic): forcedly update the result tree widget after each individual analysis (circumvents rare update issues when the ROMAlyzer isn't the active window)
fix: correctly honor the escape key in the global emulator options when its temporary search widget is hidden (i.e. cancel/close the setup dialog instead of eating the key press)
imp: SDLMESS/MESS templates updated to 0.137 (new/changed options debug_internal, natural and uimodekey)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.138 (no new or changed options)
new: added boolean option PlayOnSublistActivation to interprete item activations in search-, favorites- and played-lists as start playing commands instead of jumping to the game/machine list (default: false, current behavior)
new: added a new ROM types column to all game/machine lists and the ROM status exporter (the game/machine list cache will be updated automatically)
new: the exit/stop action now blinks when there's background activity, giving better indication of the activity itself as well as the action's second function (stop all current activity)
new: MAME targets only: added optional support for catver.ini from http://www.progettoemma.net/?catlist; this includes standard game list integration as well as two new views (view by game category / view by emulator version the game was added)
new: MP3 player: also handles MP3 streams now (simply add a valid URL instead of a file name)

v0.2.b14, 12-MAR-2010:

fix: MAME/MAMEUIFX32 templates: corrected default value for audio_latency, added new option numprocessors
fix: build: disabling joystick support caused compilation errors -- thanks to Marcelo Bossoni for reporting the issue
fix: corrected a set of initial setup issues (when there's no valid user-scope configuration for the respective QMC2 variant)
fix: corrected template checking for default values containing white-space (bug tracker ID #11)
fix: after checking icons, widget updates to the detailed game/machine list were disabled -- thanks to Robert Hamberger for reporting the issue
fix: the game/machine list header's sort indicator wasn't correctly shown when the load process finished
fix: corrected the MP3 player's internal state handling
fix: avoid crashes when switching style sheets on-the-fly
fix: avoid auto-scrolling of any game-/machine-list when returning from an embedded emulator
fix: prevent the menu-bar's context menu from being displayed (it may irritate the user that settings made through it aren't (re)stored)
fix: corrected full screen restoration on startup for desktops with multiple screens
imp: the search pattern combo box is now part of the search tab widget (which appears more intuitive and leaves vertical space for better uses)
imp: delaying initial main widget updates until all basic initializations & GUI reconstructions are finished
imp: added distribution-specific package specs to the source tree (see directory pkg-specs/)
imp: delaying automatically triggered ROM checks for 250ms (in the hope it avoids rare crashes on slower systems)
imp: nice performance improvements for ROM state filtering and loading of cached data (ROM state cache, game/machine list cache and XML cache)
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.137 (new options debug_internal, natural and uimodekey)
imp: SDLMESS/MESS templates updated to 0.136 (new option numprocessors)
imp: embedder snapshot tool: positioning the snapshot viewer more intelligently, scaling the snapshot preview down to 50% of the captured size (if its size is larger than the native resolution)
imp: build: QTDIR is no longer used -- use QMAKE instead, which defaults to qmake (that is, the qmake command found in $PATH)
imp: added new alternative image sets circles and cubes (95% the same as the classic image set, except the colored spheres are replaced with styled circles / cubes)
imp: embedder: show a message box and let the user decide if to retry an embedding operation if a window ID couldn't be found but the corresponding emulator was active at that time
imp: honoring desktop/screen geometry limits when positioning context menus
imp: setting the update delay to 'none' (0) will now cause synchronous updates when the game/machine selection changes; values higher than 0 will cause asynchronous updates just as before
imp: embedder snapshot tool: by default, take snapshots in the game's/machine's native resolution
imp: build: added the new make option L_FLAGS to pass additional flags to the linker
new: embedder: added a toggle switch for automatic horizontal maximization of embedded emulator windows
new: ROMAlyzer: CHD manager integration for optional deep verification (+ fixing) and automatic updates of CHDs -- caution: create backups before enabling the CHD manager!
new: the main widget's splitters now have their own context menus to allow for orientation flipping and swapping of their sub-widgets/sub-layouts -- this allows a free (to a certain extent) layout of all major widgets!
new: embedder: the embedder options toggle button now also includes a drop down menu (opened after a short delay when the button is held down) to terminate/kill the emulator or to add the game/machine to the favorites list (more actions may follow perhaps)
new: MAME targets only: added a demo mode which runs random games from the overall list (filtered by ROM state) for a selectable period of time -- this has been requested by some MAME cabinet users for whom it may be useful
doc: added Q3.6 and Q2.13 to FAQ

v0.2.b13, 02-JAN-2010:

fix: minor: use reverse order when loading translators (first load the Qt translations, then QMC2's translations -- Qt searches the loaded translations in reverse order, that is QMC2's translation will now be used with higher precedence)
fix: disable MAWS cache directory browse button during reload
fix: worked around a Qt bug that inhibits font changes through QApplication::setFont() when a style sheet is active
fix: restored forced backround widget updates for Qt versions >= 4.5.3 (MAWS quick links feature), delaying it to allow Qt to process all pending events (not perfect: may flicker)
fix: hide the MAWS quick links button when its menu is (auto-)hidden and the mouse cursor has left the browser widget in the meantime
fix: corrected minor focus issues after game/machine list reload
fix: MAWS lookup: don't try to download the startup URL when we're offline
fix: audio player: initially scroll playlist to the track last played (if any)
fix: using update() wherever repaint() was used to redraw game/machine images (among other things, this corrects some long-standing minor item selection issues)
imp: build: added a build configuration file for NetBSD (see arch/NetBSD.cfg) -- thanks to Jürgen Buchmüller for testing QMC2 in this environment and reporting his results
imp: SDLMAME/MAME/MAMEUIFX32 templates updated to 0.136 (SDLMAME only: new option numprocessors)
imp: SDLMESS/MESS templates updated to 0.135 (no new or changed options)
imp: added/replaced a number of embedded icons to/in the classic image set
imp: improved the error handling of the process manager
imp: build: added new make options CC_FLAGS and CXX_FLAGS to pass additional flags to the C/C++ compiler
imp: reparent the detail setup dialog to the widget it was called from (main widget or settings dialog)
imp: removed programmatic scrolling of front-end and emulator logs on new entries (using Qt's default now, which allows the user to scroll back and uses automatic scrolling when at the end of the log)
imp: improved synchronization of log browser updates
imp: minor: forcing PNG format when loading images, which offers a small performance increase
imp: during a session, the item expansion state and scroll bar values of game-/machine-specific emulator configurators are preserved
imp: using QStyledItemDelegate as base-class for item delegation (Qt recommendation)
imp: tool tips with descriptions are now also shown for the names of emulator options (not only when hovering their editors/values)
new: support for additional (foreign) emulators which can be used on a per-game/-machine basis
new: Portuguese translation by Marcelo Bossoni
new: experimental support for Qt 4.6 (note that Qt 4.5 is still the required and recommended version)
new: added new make option BROWSER_PLUGINS to enable/disable the use of browser plugins (default: disabled)
new: X11 only: added support for optional/on-demand embedding of emulator windows through the XEmbed extension (note that without minor modifications to SDLMAME/SDLMESS, there's currently no way to distinguish between multiple instances of the same emulator, running the same game/machine) -- requires xwininfo!
new: X11 only: optional embedder functions (snapshot tool, additional features planned)
new: added new make option XWININFO to supply an alternate path to xwininfo (default: "xwininfo")
new: added ability to specify a separate (i.e. fixed sized) font for all log browsers
new: except for menus, all static icons are now scaled/adjusted to the size of the current application font (even icons on the tool bar)
new: emulator configurator widgets now use check boxes (instead of combo boxes) for all boolean settings
doc: updated Q1.7.1 and Q1.7.2 in FAQ to reflect Ubuntu 9.10 and openSUSE 11.2

v0.2.b12, 01-NOV-2009:

imp: minor main widget layout improvements (MP3 player)
imp: updated redistributed Qt translations to Qt 4.5.3 and integrated them into build system
imp: new (transparent) QMC2 logo
imp: log loading of style sheets only if the name changed (this effectively suppresses the second log entry during initialization)
new: added optional live indicator for physical memory utilization to main widget
new: variant launcher: support for spawn & quit when launching another variant (optional, mainly for low memory systems)
new: template check against the running emulator's options and defaults
doc: added Q1.11 and Q2.12 to FAQ

v0.2.b11, 10-SEP-2009:

fix: corrected default short cuts for audio player functions jump to previous/next track (old short cuts were already used by X.Org X11 servers, now using Ctrl+Alt+Left/Right)
fix: custom palettes and style sheets are mutually exclusive (this fixes minor palette issues with the menu- and tool-bars when switching styles / style sheets on-the-fly)
fix: options dialog: adjusted some texts & tool tips for MESS targets
fix: corrected MOC warning for arcade/arcadeitem.h related to a missing Q_INTERFACES() statement when using Qt 4.6+

fix: clear MAWS lookup correctly when reloading game list
fix: corrected icon size adjustment for mini web browser, detail setup and ROM status exporter
fix: fixed a series of race conditions with activated Qt style sheets (Qt 4.5.2+ is recommended when using style sheets)
fix: audio player: when starting to play a new track, scroll playlist to the file currently played
fix: disable a number of widgets to avoid launching of modal dialogs when the emulator and/or game/machine info DBs are loaded (would interrupt the load progress)
imp: log discovered emulator type (MAME or MESS) together with its version
imp: download manager: remember / preselect last storage path when presenting the file name chooser, show download details in tool tip

imp: cosmetic: added detection of Windows 7 and Mac OS X 10.6 to about dialog
imp: code cleanup: set and (where possible) use QMC2_EMUTYPE_MAME/QMC2_EMUTYPE_MESS macros instead of OR'ed emulator target macros to select MAME-/MESS-only code segments
new: built-in support for dynamic loading of Qt style sheets -- note: due to a Qt bug, for now we have to change the current working directory to the style sheet's directory to make sure relative paths (image URLs) are handled correctly
new: support for PCB images as an additional game/machine detail
new: added new make option FADER_SPEED to select the speed of audio fading at build time (0: fastest/instantly, >0: slower, default: 100)
new: MAWS quick download links (manual and automatic) -- supports all available in-game previews, title snapshots, icons and cabinet art images (flyers, cabinets, control panels, marquees and PCBs)
wip: Greek translation (thanks to Giorgos Kostopoulos)
doc: adopted new homepage look to all docs

v0.2.b9, 08-JUN-2009:

imp: build: Windows: add icon to binary target exe (qmc2-emulator.exe)
new: all UI files regenerated with Qt 4.5's designer -- Qt 4.5.0+ promoted as the new required version -- Qt 4.4 is no longer supported!
new: added new make option AUDIT_WILDCARD to enable/disable the use of wildcards ('*') on full audit calls if required (default: disabled)
new: free reordering & (de)activation of all available game/machine details
new: all MAME variants now include an MAWS lookup feature as an additional game detail page (in-memory and disk-caching included)

new: all (HTTP) network access can be routed directly or via a proxy
new: added new make option BROWSER_EXTRAS to enable/disable the use of browser extra features such as Qt's Web Inspector (default: disabled) -- warning: these extra features may be buggy!

doc: changed all occurrances of external URLs to real href's (only http://... URLs supported)

v0.2.b8, 23-APR-2009:

fix: joystick calibration and test widgets: check current joystick index correctly (also fixes build issues with gcc 4.4)
fix: don't set InstanceRunning flag in the welcome dialog, but when the main widget is about to be setup (fixes cancelling/restarting with the welcome dialog)
fix: completely removed buggy settings conversion code
fix: ensure trailing slash for data-directory for path returned by standard dialog
fix: corrected variant launch on Mac OS X -- now uses LaunchServices to locate the other variant
fix: full ROM check: increase progress indicator during final determination of games/machines with a not found ROM status (or when the ROM states of all remaining systems need to become unknown due to interruption)
fix: use rompath and samplepath only if they have been explicitly set, otherwise fall back to the default paths (roms, samples)
fix: start emulator audit processes after their signals were connected (otherwise we can't be sure on all platforms that the QProcess::started() signal will be catched)
fix: insert process map entry before starting the emulation (same reason as preceding fix)
fix: ROM state toggles weren't correctly initialized at very first start
fix: corrected position restauration of image checker dialog

fix: fixed crashes when the game- or emulator-info widgets were visible during game-/machine-list reload
fix: correctly update the ROM state toggles when the ROM state filter is changed through the options dialog
imp: revised executable check of emulator binary to work platform independently
imp: SDLMAME template updated to 0.131 (new option crsshairpath)
imp: SDLMESS template updated to 0.130 (no new or changed options)
imp: completely reverted the use of wildcards (*) on full audit calls -- makes more troubles than it brings benefits
imp: ROMAlyzer: skip unsupported CHD formats
imp: pressing Qt::Key_Escape in the emulator configuration does no longer open the alphanumeric search widget, but will close it if it's currently visible
imp: updated template format to include the two new option types directory and file (new format version 0.2.2)
imp: code cleanup: replaced all occurrences of getenv("HOME") with QDir::homePath() as it is more platform independent
imp: print warnings to the front end log if emulator audit calls don't exit cleanly
imp: ROM check: set ROM status of remaining games/machines to unknown if the emulator crashes while auditing
imp: updated redistributed Qt translations to Qt 4.5.0
imp: main widget improved to allow for even more layout flexibility
imp: ROMAlyzer: changed some default settings to be more like "what the user expects"
imp: earlier initial style setup, also circumvents a minor issue with the GTK+ style
imp: worked around an annoying Qt bug that sometimes left the menu- and tool-bars at the wrong style or color palette (when changing the style dynamically)
imp: removed icon-related GUI representations for MESS targets (there are no usefull MESS machine icons we're aware of)
new: Mac and Windows only: show version of running OS on the sys-info page of the about dialog
new: show Phonon runtime version on the sys-info page of the about dialog (if applicable)
new: support for Windows^TM and the original versions of MAME & MESS (including some of their variants)

new: added new template for the original version of MESS on Windows (see data/opt/MESS/template.xml, initial version 0.130)
new: added new template for MAMEUIFX32 on Windows (see data/opt/MAMEUIFX32/template.xml, initial version 0.131) -- use this template together with the MAME variant on Windows to cleanly support MAMEUIFX32 through QMC2
new: added batch script for VC++ project file generation on Windows (see scripts/generate-vcprojects.bat -- preliminary, you'll have to adjust the path variables if you're going to use this script!)
new: added new game/machine list setting called DoubleClickActivation to let the user enable/disable the start of an emulator on mouse double-clicks (may be annoying)
new: build: added new VARIANT_LAUNCHER make option to enable/disable the QMC2 variant launcher at compile time (default: enabled on UNIX and Mac, disabled on Windows for now)
new: ROMAlyzer: support for CHD v4
new: show sort indicator in game/machine lists and let the user change the sort criteria & order by clicking an applicable column header
new: provide file & directory browsers in emulator configuration widgets where applicable

doc: revised many paragraphs to better reflect platform-specific and common information

v0.2.b7, 09-MAR-2009:

fix: ini-import/-export didn't work correctly when built for SDLMESS
fix: clear search results list when search pattern is empty
fix: ROMAlyzer: correctly reset the progress bar after analysing a game/machine for which the XML data indicates that it has no ROM files (MESS example: genesis)
fix: corrected item cursor behavior in parent/clone hierarchy view on rapidly changing selections (i.e. when hovering over the list)
fix: loading translations earlier now to allow for a translated welcome wizard
fix: SDLMESS variant: store machine-specific emulator configurations in the [MESS] section
fix: corrected a minor initial item selection issue for search results, play history and favorites lists
fix: ensure a trailing slash for preview-, flyer- and icon-directories for paths returned by the directory selection dialog
fix: corrected a series of bugs related to trimming the cached XML data -- if you don't update MAME/MESS when first using this (hopefully) fixed version of QMC2, it's recommended that you remove the gamelist- and XML-caches prior to starting QMC2 (the caches will be recreated cleanly)
fix: ROMAlyzer: use full range of main progress bar
fix: ROM state filter: correctly reset the progress bar after the filter has been applied
fix: corrected a minor style setup issue on startup

fix: center main widget on desktop if its restore position is yet undefined
imp: build: added installation of desktop entry files
imp: build: added optional support to build against a local / alternate SDL library (see new make options starting with SDLLOCAL) - the default is to use whatever SDL library the system may default to

imp: SDLMESS configuration template updated to 0.129 (revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
imp: ROM status exporter: more SDLMESS specific updates to translatable texts
imp: build: add qmc2.pro dependency for Makefile.qmake target
imp: avoid potential locking during the determination of the emulator's version & supported games/machines due to a probably failed reception of the sub-process' finished() signal
imp: ROMAlyzer: added more file status icons, log a warning on files with incorrect checksums
imp: ROMAlyzer: show count down in analyzer status
imp: code cleanup: replaced all occurrances of obsoleted QWidget method setShown() with setVisible()
imp: code cleanup: use constants instead of numbers for logical emulator options columns

imp: build: even nicer compile output
imp: more flexibility to layout the main widget (note that this can lead to unusable sub-widgets if you overdo what's possible :)
imp: ROMAlyzer: colorize wrong checksums in red, unknown states in blue
imp: build: added new ARCADE_OPENGL make option - if enabled (default), QMC2's arcade mode will support OpenGL (if available - direct rendering/hardware acceleration recommended!), otherwise only the software renderer will be available (should be fast enough, though)
imp: build: added new WIP make option - if set to 1, unfinished code will be made available (default = 0/disabled)
imp: updated redistributed Qt translations to Qt 4.4.3
imp: build: added new QT_TRANSLATION make option - set this to the absolute path to your Qt translation files if you don't want to use the ones which are redistributed with QMC2 (which is the default)
imp: welcome wizard: remove initial sample path setup for MESS variant because MESS doesn't support samples anyway
imp: added distribution specific build configuration for Mandriva Linux release 2009.0
imp: use -listfull '*' / -listxml '*' (instead of just -listfull / -listxml) to determine the total number of supported games/machines and their detailed XML data - some MAME/MESS builds wouldn't report the full game/machine list without the asterisk
imp: ROMAlyzer: log elapsed time after analysis
imp: improved full screen toggling of main widget -- should work generally better now and be more independent of the window manager
imp: build: out-of-the-box build support for Mac OS X (Darwin) -- thanks to Vas Crabb!
new: log activation of joystick support and the run-time version of SDL (if applicable)
new: show compile- and run-time versions of SDL in about dialog (if applicable)
new: log run-time version of Phonon (if applicable)

new: MESS: full device support through the new MESS device configurator, which is integrated into the main widget
new: added ROM state filter toggles to the main widget, including new short cuts
new: added new setting CheckSingleInstance (default: true) to enable/disable a startup check against multi-instance runs of the same QMC2 variant
new: all QMC2 variants are now separately configured - includes automatic settings conversion (if required) and automatic cloning of a probably already existing front end configuration (from another variant)
new: added runonce utility to project for use with the QMC2 variant launcher
new: QMC2 variant launcher: both QMC2 variants (qmc2-sdlmame & qmc2-sdlmess) can launch one another; if the other variant already runs, try raising it - note that this feature is very dependent on the window manager which may decide to ignore XMapRaised(); on KDE for example, it will only work correctly when focus under mouse or focus strictly under mouse has been set!)
wip: arcade mode (not working in this release -- disabled by default -- use "make WIP=1 ..." for a preview)
doc: added Q2.11 to FAQ
inf: checked SDL 1.3 (experimental!) compatibility of joystick API
inf: trying to build with Qt versions less than 4.4.0 is now completely inhibited!
inf: long project name changed to M.A.M.E./M.E.S.S. Catalog / Launcher II
inf: build: compile time measurement is disabled per default now
inf: there's nothing like an emulator info DB for MESS, so this feature is completely disabled in case of QMC2 for SDLMESS
inf: project home page moved to http://qmc2.arcadehits.net -- thanks to Vincent Bousquet
inf: checked Qt 4.5+ compatibility (recommended due to much better performance!)

v0.2.b6, 05-JAN-2009:

fix: startup crash on the creation of the template configuration map under certain circumstances (see tracker #2201714)
fix: worked around a minor Phonon issue with duplicate metaDataChanged() signals
imp: SDLMAME options template updated to 0.129 (corrected default value for audio_latency, revised several option descriptions, removed remapjoys and remapjoyfile, added new options joy_idx1 - joy_idx8)
imp: updated template format to include the template's emulator name (new format version 0.2.1)
imp: ROMAlyzer: determine ROM file CRC identification troubles in ZIPs, log warnings and set the file status to bad in such a case (in contrast to not found as before)
imp: code cleanup: changed several macro definitions to be consistent within QMC2's namespace
imp: build: added new make options DISTCC, DISTCC_CC & DISTCC_CXX (uses a distributed compiler such as distcc or icecc if DISTCC is set to 1 - check/set DISTCC_CC / DISTCC_CXX if enabled!)
imp: slightly improved welcome dialog (logo, button icons and layout)
imp: build: preserve existing system-wide configuration (usually /etc/qmc2/qmc2.ini) on make install
imp: build: avoid overwriting the Makefile when qmake is accidently called standalone (the project file now sets QMAKE_MAKEFILE to Makefile.qmake)
imp: build: allow pretty compile output (doesn't work for RCC yet due to a qmake bug) - enabled per default, use make PRETTY=0 to disable
imp: build: splitted CCACHECMD into CCACHE_CC & CCACHE_CXX
imp: build: use the same qmc2.pro project file for both debug and release builds (adding CONFIG settings dynamically on qmake call)
imp: ROMAlyzer: log more CHD v3 header information (CHD tag, writable flag and parent's MD5/SHA1 checksums, if applicable)
imp: ROMAlyzer: if romof is set in a game's XML data, but the file to merge is missing from this data (= merge attribute is empty), recursively search for the name of the current game's ROM file instead - MAME does exactly this in these rare cases (example: sfiiin)
imp: ROMAlyzer: produce better status and log information on CHDs that were not found
imp: allow higher values for gamelist responsiveness - setting this value higher than the total number of games will usually allow for less than 2 seconds of gamelist processing (at the expense of a more or less unresponsive GUI during reload, of course)
imp: updated XML game info parser to support all current game/machine settings from MAME/MESS
imp: many [Frontend] settings moved to [MAME] and [MESS] sections (automatically converted if the previous version is less than 0.2.b6)
imp: code cleanup: make class and variable names emulator independent (i.e. use EmulatorOptions instead of MameOptions)
new: added new SDLMESS options template (see data/opt/SDLMESS/template.xml, initial version 0.128)
new: experimental support for SDLMESS (status: very basic and no device support yet)
new: added plugin helper sample script for emulator startup interception (see scripts/plugin_helper.sh)
new: all UI files regenerated with Qt 4.4's designer - Qt 4.4.0+ promoted as the new required version, although you may still be able to build it using Qt 4.3 in the short term - Qt 4.3 is no longer supported!
new: added tab icons for all main widget functions
new: ROM status export tool with support for ASCII, CSV and HTML output formats - can output to file or clipboard

v0.2.b5, 16-OCT-2008:

fix: corrected a serious bug in ROM state and gamelist caching introduced by trimming the data - please remove all cache files from previous releases before using this version, otherwise QMC2 is likely to crash (rm ~/.qmc2/mame.lxc ~/.qmc2/qmc2.rsc ~/.qmc2/qmc2.glc)
fix: corrected the shortcut scope of several actions
fix: ROMAlyzer (cosmetic): don't start analyzing if the gamelist is empty
fix: tool bar and status bar didn't show up on first start

imp: layout improvements for the ROMAlyzer (file I/O indicator now vertical)
imp: code cleanup: prepend QMC2_ to SDLMAME macro internally
imp: build: added new make options CCACHE & CCACHECMD (uses ccache compiler cache if CCACHE is set to 1; default is 0 - check/set CCACHECMD if enabled!)

new: support for MAME output notifications via a named pipe (SDLMAME 0.127+)
new: emulator control panel changed to a multi-column tree widget displaying more information like the game name, its LEDs (if applicable), the current emulator status and additional notifiers/values not handled statically (in a sub tree)
new: added a copy command menu item to the emulator control panel's context menu to allow for easier copying of emulator command lines to the system clipboard
new: individual joystick axes can now be enabled/disabled at will (this should make Sixaxis users happy :)
new: the number of lines kept in the ROMAlyzer log can now also be limited

fix: joystick mapping initially didn't work before the options were explicitly applied
fix: keep game-specific emulator configurations open only as long as they are really needed
fix: corrected support for keyboard shortcut mapping with multiple modifier keys
imp: try to use system locale to setup the language if no language was specified (or if the language is unavailable within the translations); fallback to us as last resort
imp: joystick test and calibration widgets are enclosed in scrollable areas now to allow for better handling of high amounts of axes or buttons; due to this, the layout management for these widgets was totally revised
imp: minor speed ups for loading of XML and gamelist caches by reading data block-wise
imp: SDLMAME options template updated to 0.127 (yuvmode replaced with scalemode, removed cheat_file, added new options cheatpath, videodriver, audiodriver and gl_lib)
imp: code cleanup: use constants instead of numbers for logical gamelist columns, prepend QMC2_ to JOYSTICK and OPENGL macros internally

fix: positions of about dialog and doc browser were incorrectly restored on showEvent()'s
fix: when switching between detailed gamelist and parent/clone hierarchy during reload, QMC2 crashed under certain circumstances (not absoluteley sure if this bug existed before or if it was introduced by new features of this release :)

imp: build: moved os-detect.sh to scripts/ directory (where it belongs :)
imp: build: changed os-detection to be architecture independant for Linux distributions
new: optional use of OpenGL to draw images (previews & flyers) - decided at compile time with the new OPENGL make option (OPENGL=0 is the default and paints on a normal QWidget; using a QPainter on a QGLWidget is actually a bit slower)
new: optional direct GUI control via digital and analog joysticks (joystick support is enabled by default, use make option JOYSTICK=0 to completely disable it - note that compilation of QMC2 with enabled joystick support requires an SDL 1.2.11+ development package to be installed on your system!)

new: support for MAME's mameinfo.dat emulator information database
new: show memory information (total, free, used) in about dialog (see system info)
