* clutter/clutter-main.c:
	(unset_motion_last_actor),
	(generate_enter_leave_events): Attach a callback to the destroy
	signal on the last motion actor, so if it goes away while the
	pointer is in the middle of it we can unset the pointer.

	* clutter/clutter-private.h: Store the last motion actor inside
	the global context.
