    plug-ins: file-tiff-save looks for the wrong exif tags to delete.
    
    The correct tag for sub images is Exif.SubImage instead of
    Exif.Image. I also added Exif.Image.InterColorProfile since
    that didn't seem to get deleted when saving without
    color profile.
    
    Also added a FIXME note since most of this stuff should be
    genealized for all gimpmetadata handling.
