  User interface themes for uclient and other clients.

scratchpad
  The scratchpad is an area for various artists to work on personal and experimental projects that 
  don't fit in any of the existing categories, but that could nevertheles prove to be useful for others too. 
  Each artist can create a directory under scratchpad named as their nickname, or named after the project 
  if there's multiple people working on it. 
  For example media/scratchpad/pato/scene_setups/isometric_ground_tiles_jo.blend or media/scratchpad/syllus_comic/. 

sprites
  Isometric sprites and floor tiles.

junkyard
  A collection of old material that is currently not used, and doesn't belong in any of the other categories. 
  The junkyard is a place where you can dump things that are not needed but still are too good to throw away, 
  and where you can search for reusable parts. It differs from the scratchpad in that the material is not being 
  actively developed by anyone, and is usually old material that could not be placed elsewhere.
