	* clutter/clutter-container.[ch]: Add a generic actor container
	interface, for actors to implement without subclassing ClutterGroup.

	* clutter/clutter-group.[ch]: Make ClutterGroup implement the
	ClutterContainer interface, and deprecate the colliding methods.

	* clutter/clutter-layout.[ch]: Add extended layout interface.
	Actors and containers requiring or honouring complex layout
	management should implement this interface and provide at least
	one of the available layout types: width for height, height for
	width, natural size, iterative size request.

	* clutter/clutter-label.c: A ClutterLabel requires height for
	width layout management, so it implements the ClutterLayout
	interface.

	* clutter/Makefile.am: Add new files to the build.

	* tests/*.c:
	* examples/*.c: Update tests and examples code to use the
	new ClutterContainer API instead of ClutterGroup.
