Built from rev. 3241

* Add more information, e.g. the number of moves played, to the
  summary listed for each game in the topmost view.  There's a
  database in place now so it'll be easy to add more.

* Add zooming.  By default there's an Android zoom-controls-window
  that shows up whenever you touch the board.  There's also a new
  preference that if set causes the volume control keys to be used
  instead.

* Fix bug where screen would fail to draw and device not respond while
  it was trying to connect to the relay: moved the connection code
  into the network thread where it belongs:

* Don't show remaining tile count on board when <= 0

* Put ok/cancel buttons back on player edit dialog and relay/sms
  config dialogs.  Just feels better that way.
