* clutter/clutter-behaviour.h: Add a function prototype
	for the foreach function: we need something more specific
	than GFunc; add clutter_behaviour_get_actors(), used to
	get a list of the actors.

	* clutter/clutter-behaviour.c: Add debugging notes; add
	a warning for behaviour implementations missing the
	alpha_notify vfunc; add api documentation

	* clutter/clutter-behaviour-opacity.c:
	* clutter/clutter-behaviour-path.c:
	* clutter/clutter-behaviour-scale.c: Reimplement the
	alpha_notify functions using the new foreach function
	and, where possible, by directly iterating on the
	actors: this shaves off the number of recalculations
	of the property/alpha values, and the number of
	functions.
