	* app/widgets/gimpitemtreeview.c
	(gimp_item_tree_view_docked_iface_init): need to set
	docked_iface->get_preview to NULL explicitly now that the
	interface vtable inheriting is fixed (the layers, channels and
	paths dialogs can't show preview tabs because they don't always
	have a container).

	* app/widgets/gimpimagedock.c (gimp_image_dock_get_aux_info):
	fixed typo: s/auctive/active/. Added #defines for the magic
	aux-info identifiers to avoid bugs like that.

	* app/widgets/gimpcoloreditor.c
	* app/widgets/gimpdataeditor.c
	* app/widgets/gimppaletteeditor.c. addef #defines for aux-info
	identifiers here, too.
