	* app/widgets/gimppropwidgets.[ch]: added
	gimp_prop_expanding_frame_new() which creates a frame with a
	toggle button in the title.

	* app/tools/gimpblendoptions.c
	* app/tools/gimppaintoptions-gui.c
	* app/tools/gimprectangleoptions.c
	* app/tools/gimprectangleselectoptions.c
	* app/tools/gimpselectionoptions.c: use it instead of duplicating
	this code all over the place.
