Added Options for WebSocket.

Added WebSocketOptions class to be able to add more ClientWebSocketOptions options like KeepAliveInterval and Credentials, and a little refactoring in WebSocket.

Why wrap constructor parameters into an options object?

Why wrap constructor parameters into an options object?

since ClientWebSocketOptions has a lot of options, I would have to add a constructor for each option. so with an options object I can add options without having to mess with the original websocket.cs.
