jquery/test/unit/event.js
Ariel Flesler c0446c70d5 jquery event:
* event objects have isDefaultPrevented, isPropagationStopped and isImmediatePropagationStopped methods.
* Removed donative and dohandlers from $.trigger
* event.result carries the last returned data from a handler(not undefined).
* $.trigger doesn't keep bubbling if stopPropagation() is called.
* Same event object is used all along for global trigger
* Fixed the bug where target doesn't change when triggering on many elements.
* The data array on $.trigger was accumulating objects as it bubbles.
