WebSocket Transport support with socket.io-client-java

[gunjot-mansa]

socket.io-client-java is not able to connect with phpsocket.io while forcing websocket transport. It works perfectly fine with Polling transport but phpsocket.io throws an exception, if i force websocket transport in socket.io-client-java.

Below are warnings and exception returned by phpsocket.io

PHPSocket.IO maybe has some bug while forcing websocket transport.
But I have not much time to deal with it.
#79 seems to have fixed the problem, but I'm not sure.
Please try to check.
