screenShield: Fix pointer motion signal handler leak

Browse source 
The screen shield code listens for motion events on the stage
so that it can hide the pointer until the user moves the mouse.

Unfortunately, if the user never moves the mouse, the signal
handler connection gets leaked.

This commit makes sure the connection gets disconnected when the
shield goes away.
