Event dispatch should avoid malloc by using EventPromise

Darin had this idea a long while back.  SVG would benefit from this, see bug
16447.

Basically there would be an EventPromise object which was used during
EventDispatch (passed "const EventPromise&" up the dispatch chain), which knew
how to create an Event subclass with the right information if a listener was
found, but otherwise would avoid malloc.
