Method CloseWithJSON

websocket.go:332–369

CloseWithJSON cleanly closes the underlying WebSocket connection by sending given object (marshaled using json.Marshal()) as a close message and then waiting (with timeout) for the server to close the connection. WebSocket close code may be optionally specified. If not, then "1000 - Normal Closure"
