Game Server config runs the on_change handler on_start and on_done
Game Server config runs the on_change handler on_start and on_done

This isn't a great set up, but because of the way that the game channel is set
up it works.

The game channel just registers a callback to render the board, this makes it
so that on start and on done it will run the same callback.
