Implement for cached themes.

2004-10-21  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtkicontheme.c (gtk_icon_theme_has_icon): Implement for
	cached themes.

	* gtk/gtkiconcache.h:
	* gtk/gtkiconcache.c (_gtk_icon_cache_has_icon): New function.

	* gtk/updateiconcache.c (scan_directory): Don't skip .icon
	files which are listed before their images.
	(foreach_remove_func): Instead filter lonely .icon files out
	here.

	* gtk/gtkicontheme.c (theme_dir_get_icon_suffix): Filter out
	the HAS_ICON_FILE flag.
