Totally reworked the key grabbing, which always had problems:

 - applications get *all* key events now, as long as they have the focus
 - an application decides if it has the keyboard grabbed or not
 - if it's grabbed, the app consumes the key press
 - if it's not grabbed and a F1-F29 key is pressed, the app sends a QCop
   call to the launcher (deviceButtonPressed(...))
 - when the launcher receives a QCop deviceButtonPressed it simply sends
   the configured QCopEnvelope
 - all "special" actions (like menu, home) are now accessible via QCop
   calls (see buttonsettings)
