        * configure.ac Makefile.am: auto-ize.

        * xdgmime/: Add freedesktop.org MIME spec implementatin
        by Jonathan Blandford.

        * gtkfilesystem.[ch]: Add gtk_file_info_render_icon()
        gtk_file_info_set/get_icon_type to do icon handling
        based on MIME type. Add a simple icon caching system.

        * gtkfilesystemgnomevfs.c: Implement ensure_types()
        so that extending the set of types for a loaded
        directory works. Set the MIME type to get the default
        icon handling.

        * gtkfilesystemunix.c: Look up the MIME type using
        xdgmime.

        * gtkfilechooserimpldefault.c: Display icons in the list.
