	* app/menus/plug-in-menus.c (plug_in_menus_add_proc): create
	dynamic sub-menus using a separate, ui-manager-global merge_id
	instead of the procedure's merge_id. Has the effect that the ui
	manager keeps around these sub-menus forever, even if the
	procedure that initially registered them is unregistered.
	Fixes menu ordering after Script-Fu->Refresh.
