Chess: Gracefully handle ChessEngine disconnections

Browse source 
The GUI now tracks when it becomes disconnected from ChessEngine.
If not currently waiting for a move from ChessEngine, it will
automatically reconnect on the next engine move. If a disconnection
occurs while waiting for a move, the player is asked whether they
want to try again or not.
