	More unused action stuff:

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpactionfactory.[ch]: added a simple factory which
	produces GimpActionGroups.

	* app/widgets/gimpactiongroup.[ch]: added an "update_func" member
	to the GimpActionGroup struct. Added it as parameter to
	gimp_action_group_new(). Added function gimp_action_group_update().

	member and constructor parameter. Added code to create
	GtkUIManagers from registered action group identifiers.

	* app/actions/Makefile.am
	* app/actions/actions.[ch]: new files: create a
	"global_action_factory" and register all action groups with it.

	* app/actions/plug-in-actions.[ch]: added API to add/remove
	plug-in procedure actions dynamically (unfinished).
