Change the web socket interface

Change the web socket interface

The stream of events from a web socket is now the actual messages
(text as String and binary as List<int>) instead of instances of
MessageEvent. The CloseEvent is reposted as onDone on the stream with
the close code and close reason available as properties on the web
socket object.

Next step is to make the web socket implement IOSink.
