[Transitions] Add a convenience property for determining if an element is in transition.

The current Transitions Events API[1] does not provide a convenience
property for determining if an element is in transition.

Unrelated, but also annoying is that the transitionEnd event fires for
each property transitioned, but there is no event that fires when all
of the transitions have finished.
