/** Sligtly modified QApplication class.
*
* The sole purpose of this class (ATM) is to hook the macEventFilter
* in order to intercept Command-Q, Command-H and similar menu hot-keys
* before the HI Manager translate them into (menu) command events and
* start blinking menus in the menu bar.
*
* @remark
* A special hack in qeventloop_mac.cpp is required for this
* to work. Overloading QEventLoop::processEvents isn't feasable
* unfortunately, thus the horrible hacks. Qt 4 does seem to provide
* an interface similar to the one we create here.
*
* Btw. is QI* the right right way to do this? Or should it perhapse
* be called VBoxQApplication or something?
