Added a server managed notion of which client is controlling the game.

Doing this on the client, while theoretically possible, is more complex. We
have a server, we use it to provide commonly needed services, the assignment of
a single client to control the game is a commonly needed service. This also
matches the way other services like turn change and game start and end are
implemented.

A side note: the client-side code was not properly handling disconnected
players, which the server code properly handles.
