Subject: [PATCH] window-list: drop button grab when leaving button

StButton doesn't always drop its grab, if the user releases the
mouse over the wrong part of the screen.

This commit works around the problem by pretending the user
lift their finger from the mouse as soon as they leave the
boundaries of the button actor.
