Transition object needs to clear its state in the controller

[jverkoey]

The controller holds onto a reference of the transition but never releases it. It should release the transition instance when the transition completes.

The transition should provide a delegate that the controller can assign itself to in order to receive a "didFinish" event. The controller should nil out the transition instance when this event is received.
