Cyrillic natural order sorting

strnatcasecmp have bug with cyrillic characters and UTF-8 encoding. This module use next constraction for sort by title:

 function _cctags_sort_by_title($a, $b) {
  return strnatcasecmp($a->name, $b->name);
} 

Working constration is something like:

 function _cctags_sort_by_title($a, $b) {
  $namea = iconv('UTF-8', 'cp1251',$a->name);
  $nameb = iconv('UTF-8', 'cp1251',$b->name);
  $namea = cyr_strtolower($namea);
  $nameb = cyr_strtolower($nameb);
  return strnatcasecmp($namea, $nameb);
}
