[Qt] Qt session management

[zeljko]

Hi all,
We have an issue about this
http://bugs.freepascal.org/view.php?id=18910
and it seem it's impossible to fix it without new bindings.
There are my comments and conclusions, also links to session management under 
qt.
Den, please if bindings changes are planned, do not forget to add 
QSessionManager implementation, and also QApplication signals 
commitDataRequest() and saveStateRequest() - maybe those 2 are enought even 
without QSessionManager implementation.
There's already event type defined for this signals, but no implementation to 
hook that event (QApplication_hook_hook_commitDataRequest & 
QApplication_hook_hook_saveStateRequest is missing).
