* clutter/clutter-alpha.h:
	* clutter/clutter-alpha.c: ClutterAlpha is an initially
	floating object, as it makes sense only when bound to
	a ClutterBehaviour; add checks for public API.

	* clutter/clutter-behaviour.h:
	* clutter/clutter-behaviour.c: Remove the ClutterBehaviour
	constructor: ClutterBehaviour is an abstract class which
	must be implemented by subclassing; add checks for public
	API; unref the actors on finalize; sink the ClutterAlpha
	object.

	* clutter/clutter-behaviours.h: ClutterKnot is a boxed
	type: add the _get_type() function declaration and the
	type macro.
