	* menus/Makefile.am
	* menus/gtkuimanager.dtd: added a DTD (basically copied from the
	GTK+ API docs). Added a "validate" rule that allows to easily
	validate the XML files.

	* menus/*.xml: added a DOCTYPE declaration that refers to the
	newly added DTD.

	* app/widgets/gimpenumstore.[ch]:
	* app/widgets/gimpenumcombobox.c: documented the new API.
