Enhanced Compiz support
Added preliminary ability for allowing specific hotkeys to execute global shortcut actions while the desktop lock is active. The primary use for this is to switch monitors while the screen is still locked (with the switch-monitor hotkey) so that the user can login. git-svn-id: svn://anonsvn.kde.org/home/kde/branches/trinity/kdebase@1116279 283d02a7-25f6-0310-bc7c-ecb5cbfe19da
