register GIMP_TYPE_DASH_PATTERN as boxed type. Added "new" to function 

2007-01-12  Michael Natterer  <mitch@gimp.org>

	* app/core/gimpdashpattern.[ch]: register GIMP_TYPE_DASH_PATTERN
	as boxed type. Added "new" to function names which create dash
	patterns. Changed and renamed GValue functions to functions which
	convert the dash pattern between GArray and GValueArray.

	* app/core/gimpstrokeoptions.c
	* app/widgets/gimpcellrendererdashes.c
	* app/widgets/gimpstrokeeditor.c: changed accordingly.

	* app/widgets/gimpdasheditor.c: ditto. Get rid of the recently
	added manual memory management. The list store manages boxed types
	all by itself.
