Emmanuele Bassi fe11263b84 2007-07-22 Emmanuele Bassi <ebassi@openedhand.com>
* clutter/clutter-behaviour.[ch]: Rename ClutterBehaviour::apply
	and ClutterBehaviour::remove to ClutterBehaviour::applied and
	ClutterBehaviour::removed respectively, and emit them when the
	behaviour has been applied (or does no longer apply) to an actor.

	(clutter_behaviour_dispose), (clutter_behaviour_finalize),
	(clutter_behaviour_class_init): Move the actor removal to the
	::dispose virtual function, and remove the ::finalize one;
	document the missing properties and signals.

	(clutter_behaviour_clear): Add function to clear a behaviour:
	every actor will be unreffed and the ClutterBehaviour::removed
	signal will be emitted.
