	* app/core/gimpviewable.[ch]: added "gchar *name_changed_signal"
	to GimpViewableClass which defaults to "name_changed".

	* app/widgets/gimplistitem.c
	* app/widgets/gimpmenuitem.c: connect to
	viewable_class->name_changed_signal instead of just
	"name_changed". Fixed possible UI inconsistency where the previous
	viewable's tooltip would have been displayed.

	* app/core/gimpimagefile.[ch]: set name_changed_signal to
	"info_changed" so views can update their tooltips correctly.
	Merged the separate image_state and thumb_state states into one
	state variable and extended the state enum. Added description
	strings for all states. Show the file size for all files, not only
	for those with a thumbnail. Enabled display of outdated
	thumbnails.

	* app/gui/file-open-dialog.c: some changes because
	gimp_imagefile_get_description() returns 3 instead of 2 lines of
	text now.

	* app/widgets/gimpcontainerview-utils.c: show the imagefile's
	description in the tooltip.

	* app/gui/menus.c
	* app/gui/documents-commands.[ch]
	* app/widgets/gimpdocumentview.c: added functions to remove
	"dangling" document history entries. Updated the context menu so
	all functions can be accessed through it.
