	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpaction.[ch]: new GtkAction subclass which can
	show either a color or viewable preview in GtkImageMenuItem
	proxies.

	* app/widgets/gimpenumaction.[ch]
	* app/widgets/gimppluginaction.[ch]
	* app/widgets/gimpstringaction.[ch]: derive them from GimpAction.

	* app/widgets/gimpactiongroup.c (gimp_action_group_add_actions):
	add GimpActions, not GtkActions.

	(gimp_action_group_set_action_color)
	(gimp_action_group_set_action_viewable): removed all hacks and
	simply set the "color" or "viewable" properties of the GimpAction
	to change. Fixes color/viewable previews in menus.

	* app/actions/file-actions.c: show previews in the "Open Recent"
	menu items.

	Unrelated:

	* app/widgets/widgets-types.h: removed GimpDockedInterface typedef...

	* app/widgets/gimpdocked.h: ...and added it here. We don't have
	class struct typedefs in the types header either.

	* app/actions/edit-actions.c: added <Ctrl>+semicolon as shortcut
	for "edit-fill-pattern".

	* app/actions/gradient-editor-actions.c: added some stock IDs.
	Please comment.
