* clutter/clutter-rectangle.h:
	* clutter/clutter-rectangle.c: Add border to the ClutterRectangle
	actor; add "border-width", "border-color" and "has-border"
	properties, plus their accessors.  The border generation code is
	pretty lame, at the moment.

	* examples/behave.c: Add code to test the new rectangle properties.
