[rygel/rygel-0-12] playbin: Add support for image/jpeg and image/png

[Jens Georg <jensgeorg src gnome org>]

    playbin: Add support for image/jpeg and image/png
    
    Use the typefind element of Playbin2 to determine if we're rendering an
    image since UPnP allows the meta-data to be empty and it may not be
    possible to guess the type from the URI.
