* clutter/clutter-private.h: Add our own READABLE,
	WRITABLE and READWRITE paramspec flags, declaring the
	string components of the properties GParamSpec as static;
	this should shave off some bytes in the memory footprint
	and avoid relocations.

	* clutter/clutter-actor.c:
	* clutter/clutter-behaviour.c:
	* clutter/clutter-behaviour-opacity.c:
	* clutter/clutter-behaviour-path.c:
	* clutter/clutter-behavuour-scale.c:
	* clutter/clutter-clone-texture.c:
	* clutter/clutter-label.c:
	* clutter/clutter-rectangle.c:
	* clutter/clutter-stage.c:
	* clutter/clutter-texture.c:
	* clutter/clutter-timeline.c: Use the CLUTTER_PARAM_*
	macros we just added.

	* clutter/clutter-behaviour-scale.c: Add properties for
	the scale begin, scale end and gravity parameters.

	* clutter/clutter-behaviour-path.h: Mark the ClutterKnot
	memory management functions as public (for the bindings),
	since we use the slice allocator for copying knots around;
	add a clutter_knot_equal() function.

	* clutter/clutter-behaviour-path.c:
	(node_distance): Use clutter_knot_equal() as a fast path
	to avoid the sqrt() in case the nodes we are using are
	at the same position.
	(path_total_length): Additional check on the existence
	of the next node.

	* examples/behave.c: Do not leak the ClutterBehaviour
	objects around.
