Subject: fix(browserTrigger): do not use document.createEvent method

Firefox 23 has deprecated the use of createEvent for transition and
animation events.  We must now use `new TransitionEvent()` and
`new AnimationEvent()` if they are available.

But of course IE doesn't support this format correctly so we must wrap
the attempt in a try block and revert to document.createEvent if necessary..
