	Added GtkTreeView versions of layers/channels/vectors:

	* app/core/core-enums.[ch]: renamed GIMP_UNDO_GROUP_LAYER_PROPERTIES
	to GIMP_UNDO_GROUP_ITEM_PROPERTIES.

	* app/core/gimpcontainer.c (gimp_container_reorder): don't try
	to reorder containers with num_children == 1.

	* app/core/gimpmarshal.list: added VOID: STRING, UINT marshaller.

	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpchanneltreeview.[ch]
	* app/widgets/gimpdrawabletreeview.[ch]
	* app/widgets/gimpitemtreeview.[ch]
	* app/widgets/gimplayertreeview.[ch]
	* app/widgets/gimpvectorstreeview.[ch]: new widgets.

	* app/widgets/gimpcellrenderertoggle.c: draw the frame only if the
	cell is prelit.

	* app/widgets/gimpcellrendererviewable.[ch]: added "clicked"
	signal, unref the renderer in finalize(). Set the renderer's
	border color to black if the cell is not selected (a hack that
	saves tons of code in GimpLayerTreeView).

	* app/widgets/gimpcomponenteditor.c: no need to gtk_list_store_set()
	stuff we just got from the store.

	* app/widgets/gimpcontainertreeview.[ch]: added lots of state used
	by the new subclasses to the GimpContainerTreeView struct.  Create
	the GtkListStore/GtkTreeView in GObject::constructor() and only
	collect parameters in init() so subclasses can modify store/view
	creation. Do most of the button_press_event stuff manually and
	return TRUE from the handler.

	* app/widgets/gimpcontainerview.c: cleanup.

	* app/widgets/gimpitemlistview.h
	* app/widgets/gimpvectorslistview.h: temp hacks before they die.

	* app/widgets/gimppreviewrenderer.[ch]: added
	gimp_preview_renderer_update_idle() which idle-emits "update"
	without invalidating.

	* app/gui/dialogs-constructors.[ch]
	* app/gui/dialogs.c: added constructors for the new dialogs.

	* app/gui/channels-commands.c
	* app/gui/channels-menu.c
	* app/gui/layers-commands.c
	* app/gui/layers-menu.c
	* app/gui/vectors-commands.c
	* app/gui/vectors-menu.c: accept tree views as callback data.
