olly 4828f275c7 Make play button behave differently in IDLE and ENDED states
- In IDLE, the button will now call a preparer. This allows
  removal of the separate retry button from the demo app.
- In ENDED, the button will seek back to the default position
  and play.
- Behavior is made consistent with LeanbackPlayerAdapter.
