      Description

      hi all,

      the current implementation of FSDirectory.create(...) silently deletes all files
      (even empty directories) within the index directory when setting up a new index
      with create option enabled. Lucene doesn't care when deleting files in the index
      directory if they belong to lucene or not. I don't think that this is a real
      bug, but it can be a pain if somebody whants to store some private information
      in the lucene index directory, e.g some configuration files.

      Therefore i implemented a FileFilter which knows about the internal lucene file
      extensions, so that all other files would never get touched when creating a new
      index. The current patch is an enhancement in FSDirectory only. I don't think
      that there is a need to make it available in the Directory class and change all
      it's depending classes.

      regards
      Bernhard
