fixed bugs 5674, 5697 and 5699, Nautilus shows a broken image icon instead

	fixed bugs 5674, 5697 and 5699, Nautilus shows a broken image
	icon instead of a mime-type icon for image types that it doesn't
	support.  Fixed by generating a zero-length placeholder thumbnail
	instead of the broken image icon; the icon factory tests for the
	placeholder and uses the proper mime-type icon when it's present.

	* libnautilus-extensions/nautilus-icon-factory.c:
	(should_display_image_file_as_itself),
	(nautilus_icon_factory_get_icon_for_file):
	made should_display_image_file_as_itself return FALSE when the
	placeholder is present.

	* libnautilus-extensions/nautilus-thumbnails.c:
	(make_invalid_thumbnail_uri),
	(nautilus_thumbnail_has_invalid_thumbnail), (check_for_thumbnails):
	added routine to test if a placeholder is present, and made it
	generate the placeholder when thumbnailing fails.

	* libnautilus-extensions/nautilus-thumbnails.h:
	added nautilus_thumbnail_has_invalid_thumbnail
