Views handler for userpoints transaction status

In current version, userpoints transaction status is displayed as numeric field. It makes no sense out of the box.
A simple handler displaying translated string for status would be more appropriate.

class userpoints_views_handler_field_status extends views_handler_field {
  function render($values) {
    $value = $this->get_value($values);
    $statuses = userpoints_txn_status();
    if (isset($statuses[$value])) {
      return $statuses[$value];
    }
    else {
      return '';
    } 
  } 
}
