XSS-Track as a HTML5 WebSockets traffic sniffer

Kotowicz extends XSS-Track so one injected script sniffs HTML5 WebSocket traffic. It wraps window.WebSocket, replacing the constructor and prototype.send and attaching a message listener, so every frame sent and received is logged to the attacker's backend - showing ws:// is no safe channel for private data on a page with any XSS.
