Improper file root

you should not hard code /files in the function og_files_base_path.

Some of us move this to /sites/sitename/files for multisites.

Not sure what to patch since the latest working version at http://drupal.org/node/212572#comment-699916
is full of whitespaces..

so here is the fix:

function og_files_base_path($gid) {
  $drupal_files = file_directory_path();
  return  $drupal_files .'/og_files/'.$gid.'/';
}

thanks for a handy little module.
