Subject: [PATCH] * Adjusted themes.inc to make it bullet-proof.  The theme
 problem hasn't   been fixed yet though, but at least it won't try to load
 non-existing   themes.  That is, you might not be able to select your
 prefered theme,   but you should be able to surf the pages with the default
 theme no   matter what.  Hence, it semi-fixes the theme problem reported
 earlier   by UnConeD.

  Natrak: make sure the new user system won't suffer the same problem.
          Use file_exists(string filename) to check whether the theme
          does actually exist.  If not, load the default theme.
