Autobahn does not comply with Android Strict Mode

[jschmid]

If you try to enable StrictMode, specifically untagged sockets, the app will trigger warnings (or crash if it is configured as such) because of the socket opened by Autobahn.

This is a bit annoying because this prevents us to use the "catch all" detectAll() method from StrictMode.

From what I understand, WebSocketConnector should call TrafficStats.setThreadStatsTag(int) to use a TAG for the socket created by Autobahn.
