* qt4/Alert_pimpl.C: make sure the proper Qt attributes are set.
* GuiApplication::quitLyx(): add the "force" argument to the funcRequest.
* GuiImplementation:
- GuiImplementation(): remove the signal connection. This was triggered after the LastWindowClosed signal so was not useful.
- cleanupViews(): renamed to unregisterView() and handle the WorkAreas as well.
- closeAll(): new method (from LyXView).
* GuiView.C
- clean up the includes order.
- closeEvent(): make sure that theBufferList().quitWriteAll() is called if last window closed.
* lyx_main.C / LyX::quit():
- remove noAsk argument
- delete bufferList::quitWriteAll() call (this is handled in the frontend).
- delete Session stuff (ditto)
* LyXFunc::dispatch()
- LFUN_LYX_EXIT: close all window before exiting from user command (as opposed to last window closed).
