Screen saver format - application/x-pmd

The LG PM-325 stores it's screen saver formats in the wallpaper index list.  So, by default I'm pulling down the file as part of wallpaper handling.  But the viewer can't handle the format.  I'm going to hit the archives but I didn't see code (yet) in the other phones dropping some of these formats.  There is a file called (nn).gcd in the same directory that contains text defining the image type, and it has a content type of "application/x-pmd".
