A new internal API has been created for use by assistant
to launch an Activity Transition from a non-Activity.
The ActivityOptions are also passed along when using
a spring board Activity so that the shared elements
can be properly synchronized.
This also fixes TransitionManager.endTransition so
that it forces Transitions to end the animations.
