Fix NPE in "/chess board set" tab completion when not on board
Added selected square highlighting
Selected square is now a property of the board, not the game

responsible for board & game deletion.  Boards & games don't delete
themselves.
Now less verbose by default.  Added "verbose" config setting.
And clicking a board square with one of your pieces on it will now
select that piece, if it's your move.
Entity boards!
Using RemoteEntities.  It basically works, but there still is a lot of
flakiness to deal with.
