	* libgimpwidgets/gimphelpui.[ch]: added gimp_help_id_quark()
	which is G_GNUC_CONST and a new macro GIMP_HELP_ID as shortcut.

	* app/widgets/gimpactiongroup.c (gimp_action_group_add_*_actions):
	attach the help ID to the action using the new quark key. Call
	gtk_action_group_add_action() instead of the _with_accel() variant
	if the accel is the empty string (== if we explicitely want no
	accel even if the stock item specifies one). Fixes warning flood
	with GTK+ 2.4.1.
