Multilingual Multireference

In order to make it more complete multilingual some more translations are needed

//in multireference.module line 492 wrapped descriptions with t()
      // add description fields
      $header = '<td>'. t($field['t_desc']) .'</td><td>'. t($field['t_ref']) .'<td></td>';
      if ($field['desc2_provide']) {
        $header .= '<td>'. t($field['t_desc2']) .'</td>';
      }

and also

//in multireference.module line 595 wrapped "add another field" with t()
      $form[$fieldname]['item_add'] = array(
        '#value' => '<tr><td><a href="#multireference_anchor_'. $fieldname .'" class="multireference_add_fields" next_item="'. $tbl_i .'" field_name="'. $fieldname .'">[+] '.t("add another field").'</a></td></tr>',
      );
