This looks questinonable. We don't reuse events like this anywhere else. Tooltip ends up changing `event.type`, but it doesn't trigger a native event. Widget sets `event.type`, but only on a `$.Event` instance. That's likely the thing to do here, too:

```js
var newEvent = $.Event( event );
newEvent.type = "click";
this.element.trigger( newEvent );
```

I might be wrong about that, since here we try to imitate the native event. I guess this is still better then what we had before. @scottgonzalez what do you think about this?
