By deprecating faye and celluloid you got rid of the websocket libraries that supported a proxy. #366

I used to be able to connect to Slack's websocket via a proxy, but with the new code it doesn't connect at all.

It's able to receive the rtm start response, but it can't actually talk to the web socket because async-websocket doesn't support using a proxy to reach a web socket.

Celluloid did, and I was using it. I think faye did. Apparently async-websocket does since...around...0.14.0, roughly a year ago, but this client requires 0.8.0, from about two years ago.

What's preventing an upgrade to a more recent async-websocket?

I tried a while ago and it didn't just work out of the box. Would love a PR. See #282
