 * `jQuery.fn.triggerAsync(type, [data], [success], [prevented]` triggers an event and calls success
 * when the event has finished propagating through the DOM and no other handler
 * called `event.preventDefault()` or returned `false`.
 *
 *     $('#panel').triggerAsync('show', function() {
 *        $('#panel').show();
 *     });
 *
 * You can also provide a callback that gets called if `event.preventDefault()` was called on the event:
 *
 *     $('panel').triggerAsync('show', function(){
 *         $('#panel').show();
 *     },function(){ 
 *         $('#other').addClass('error');
 *     });
 *
 * @param {String} type The type of event
 * @param {Object} data The data for the event
 * @param {Function} success a callback function which occurs upon success
 * @param {Function} prevented a callback function which occurs if preventDefault was called
