Added ConnectionToServerCommandFactory, and JoinSuccessfulCommand, RaceParticipantsFullCOmmand, ServerFullCommand. Added IncomingHeartBeatCommandFactory, and IncomingHeartBeatCommand. Added ConnectionToServerState, which represents the client's connection state to server. Renamed VisualiserInput to VisualiserRaceController. Added ConnectionToServer, which tracks the client's connection to server. Added ConnectionToServerController, which accepts JoinAcceptance messages, turns them into commands, and passes them to ConnectionToServer. Added IncomingHeartBeatService, which tracks the heart beat status of the connection. Added IncomingHeartBeatController, which accepts HeartBeat messages, turns them into commands, and passes them to IncomingHeartBeatService. Refactored ServerConnection a bit. #story[1095]
