 * Description: Normalize all greet messages set with NickServ             *
 *                                                                         *
 *   When this module is loaded, all greet messages being set via NickServ *
 *   SET GREET will be stripped from color, bold, underline, and other     *
 *   control codes, making sure that they won't exist in the greets.       *
 *                                                                         *
 *   No configuration needed, it just works (tm).                          *
 *                                                                         *
