Added delayed motion notify event handling, this way we can
	discard redrawing if more than 25 events arrive per second.

	* src/hildon-pannable-area.c,
	(hildon_pannable_area_init): Initialized the new private atributes
	controlling this timeout
	(hildon_pannable_area_dispose): Remove the timeout that controls
	the motion notify events.
	(hildon_pannable_area_scroll): Added a condition to control the
	use of the acceleration.
	(hildon_pannable_area_motion_event_scroll_timeout),
	(hildon_pannable_area_motion_event_scroll): Added this two
	functions, they handle the motion notify events inside the
	timeout.
	(hildon_pannable_area_motion_notify_cb): Replaced the direct call
	to the scroll method with the new function.
	(hildon_pannable_area_button_release_cb): We have to remove the
	timeout handler and move to the last position if the last motion
	events were not handled.

	Fixes: NB#97028 (Pannable area updates on every motion event)
