In-app launcher for Mac, based on Qt5. The old Mac launcher doesn’t work on Yosemite, add a tiny Qt-based launcher inside the main process (no need to fork / exec) which runs before the OSG window is created. Will be merged for 3.4, hopefully with no impact on other platforms.

Split flightgear::initApp() to make it usable even without FGGlobals initialized - Add an optional argument to flightgear::initApp(): doInitQSettings. This argument defaults to true, preserving initApp()'s behavior in this respect. If this argument is set to false, FGGlobals doesn't have to be initialized. - New function flightgear::initQSettings(), called by flightgear::initApp() when its 'doInitQSettings' argument is true. This allows initializing the QSettings exactly when it is needed. - New function flightgear::checkKeyboardModifiersForSettingFGRoot(). The code it contains used to be run from initApp(), which is undesirable because: 1) initApp() is not only called at FG initialization (fgMainInit()), but also from QtMessageBox(), from QtFileDialog::exec() and twice from Options::setupRoot(). However, checking the Alt and Shift modifiers to set 'fg-root' in QSettings to the special value "!ask" only makes sense in fgMainInit(), not in these other places. 2) This code relies on the QSettings to be set up, and therefore on FGGlobals. Thus, freeing initApp() of its dependency on FGGlobals requires splitting this keyboard modifiers checking code out of initApp().

Fix intermittent crash on exit with Qt+XCB We can still crash on exit(-1) code paths since we can’t run this from atexit, but at least the non-error paths are ok.

Split the launcher main window into its own file. Reduces QtLauncher.cxx down to the public API and the static helper methods; the main window lives in its own file.
