Subject: [PATCH] umoria: refactor and extend

- Simplify some symlinking
- Don't remove the temporary run directory: umoria allows for dumping
  character info, which would be in there and inaccessible after
  saving the game otherwise.  The system takes care of cleaning up
  the temporary directory anyway.
- Allow passing arguments to the wrapped executable, allowing using
  different save directories, passing game seeds, checking out
  highscores, etc.
