Ring websocket API support

[weavejester]

I've been working on a Ring websocket API that's currently in experimental alpha. Would you be interested in a PR to support this in http-kit, to be merged when the Ring websocket API is stable? It would obviously be supported in conjunction with http-kit's native implementation.

The reason I'm asking this while the Ring API is still experimental is that I'd like to try implementing the API for different third-party adapters, so I can get feedback and forewarning of any design issues. I've submitted a similar issue to the ring-jetty9-adapter project.

@weavejester Hi James, would be very interested in a PR - that'd be great!

Thanks so much for thinking of http-kit, cheers :-)

No problem! My current plan is to add a pongHandler to AsyncChannel, and create a PingMessage and PongMessage class for use with AsyncChannel.send, in order to allow the ping/pong support that the Ring websocket spec requires. Does this seem a reasonable approach?

I'm not familiar with the Ring websocket spec, but your plan sounds very reasonable from http-kit's end 👍
