Should have support for all native events

[btford]

See:

• https://developer.mozilla.org/en-US/docs/Web/API/WebSocket
• http://www.w3.org/TR/websockets/

Events:

• [ ] onclose
• [ ] onerror
• [ ] onmessage
• [ ] onopen

You always can access underlying websocket object but I agree it's needed. Actually it stopped me partly from using this library in my recent project. +1

+1, onclose and onerror are needed.
