	The unbelievable happened: a menu bar per display (optionally)

	* app/widgets/gimpitemfactory.[ch]: Added the possibility to have
	more than one item factory per <Prefix>. Added
	gimp_item_factories_set_foobar() variants of all functions which
	set menu item properties (label, sensitive, ...). Removed
	the #ifndef ENABLE_NLS code since that's no longer possible.

	* app/widgets/gimptoolbox.c: made it robust againt the <Image>
	factory not existing at the time of toolbox creation.

	* app/config/gimpconfig-blurbs.h
	* app/config/gimpdisplayconfig.[ch]: added boolean
	"menu_bar_per_display" property.

	* app/gui/preferences-dialog.c: added a toggle for the new option.

	* app/gui/menus.[ch]: added menus_get_new_image_factory() as
	temporary solution. Will add a GimpMenuFactory which creates the
	item factories soon.

	* app/display/gimpdisplayshell.c: add the menu bar if requested.
	Changed widget packing slightly for the menu bar case.

	* app/display/gimpdisplayshell-callbacks.c: changed accordingly.
	Currently there is no right-click popup menu when we have a menu
	bar. This will change soon.

	* app/gui/file-dialog-utils.c
	* app/gui/gui.c: use gimp_item_factories_set_foo().

	* app/gui/channels-commands.c
	* app/gui/dialogs-commands.c
	* app/gui/dialogs-constructors.c
	* app/gui/drawable-commands.c
	* app/gui/edit-commands.c
	* app/gui/file-commands.c
	* app/gui/image-commands.c
	* app/gui/layers-commands.c
	* app/gui/plug-in-commands.c
	* app/gui/select-commands.c
	* app/gui/tools-commands.c
	* app/gui/vectors-commands.c
	* app/gui/view-commands.c: per-display item factories pass the
	GimpDisplay as user_data to callbacks, not a Gimp. Changed all
	return_if_no_foo() macros to handle both cases.

	Cleaned up the plug-in menu stuff:

	* app/plug-in/plug-in-types.h: removed PlugInMenuEntry type.

	* app/plug-in/plug-ins.[ch]: added plug_ins_proc_def_add() as
	counterpart to plug_ins_proc_def_remove(). Added
	plug_ins_locale_domain() as counterpart to plug_ins_help_path().
	Remember the locale domains just as the help paths. Changed
	plug-in initialization so that their menus can be created multiple
	times.

	* app/plug-in/plug-in.[ch]: use plug_ins_proc_def_add() instead of
	doing it manually.

	* app/gui/plug-in-menus.[ch]: added plug_in_menus_init() which
	just registers the locale domains. Changed plug_in_make_menu() to
	take a list of proc_defs, not plug_ins_defs so it can be used
	after plug-in query.
