	* libgimp/gimpmenu.h: changed the return value of
	GimpConstraintFunc from gint to gboolean.

	* libgimp/gimpmenu.c: fixed bug introduced by my latest cleanup:
	Don't free the drawable arrays after creating the menus since they
	are used in the callbacks. Instead, free them using a GWeakNotify
	on the menu. Factored menu and item creation out to utility
	functions to reduce code duplication. Cleanup.
