Get Autobahn passing arbitrary events

[kousu]

Play with autobahn until it goes.

Tnings to try:

• Can we get websockets working under twisted without it? (test: open up the chrome inspector and run the websocket sample code at MDN)
• Maybe Autobahn-twisted is fine but Maybe it's just the frontend, Autobahn.js, that's being glitchy.

As we do this, DOCUMENT the process at APIs
