Event.target not properly set through constructor

In the Event constructor, $target is never set properly. The fix is easy (surely a copy-paste error)

In :

  $debug("Creating new Event");
  var $bubbles = options.bubbles?options.bubbles:true,

  $cancelable = options.cancelable?options.cancelable:true,
  $currentTarget = options.currentTarget?options.currentTarget:null,
  $eventPhase = options.eventPhase?options.eventPhase:Event.CAPTURING_PHASE,
  $target = options.eventPhase?options.eventPhase:document,
  $timestamp = options.timestamp?options.timestamp:new Date().getTime().toString(),
  $type = options.type?options.type:&quot;&quot;;</code>

Change the line

      $target = options.eventPhase?options.eventPhase:document,

to

      $target = options.target?options.target:document,
