Use gradle 2.1, and version 0.14.0 of the Gradle plugin.

(cherry picked from commit 9adfd8ba1f7e0d07116bf36beae0bc7b2d9eed6c)
Save the current playlist name when parceling a PlayerState.
Handle sub menu items in player context menus (sleep durations).
Show sleep information for players other than the active player.

The server does not respond with status updates as the will_sleep_in
timer counts down, so players with a count down to sleep need to have
second-to-second status updates enabled.

- Move the PlayerSubscriptionType enum in to PlayerState.

- Keep track of the player's subscription state on an on-going basis.

- Determine the appropriate player subscription state every time a
  status line is received, and update as necessary (e.g., if the
  player has started counting down to sleep).
