Subject: - very effective optimization to findfirstfile-calls - several
 configuration files are now only saved to disk if the content actually
 changed.   This should also get rid of a problem where plugins.txt was
 re-written immediately after starting the game   (causing a conflict with the
 game) - reduced "noise" from hook.dll - removed some debugging messages
