* Extension of the Symfony2 EventDispatcher
*
* It provides an additional `trigger_event` method, which
* gives some syntactic sugar for dispatching events. Instead
* of creating the event object, the method will do that for
* you.
*
* Example:
*
*     $vars = array('page_title');
*     extract($phpbb_dispatcher->trigger_event('core.index', compact($vars)));
