ScreenShield: send a signal to GSD to wake up the screen

Browse Source 
Instead of poking through IDLETIME, which confuses the state tracking
and can prevent automatic suspend, send a special signal to GSD
when the screen is to be waken up for a notification.

Someday we'll bring over all the state tracking and avoid this
ping-pong between gnome-shell and gnome-settings-daemon, but
that day's not today.
