Configurable Multi Channel Chat Support

[rmattam]

An attempt to write idiomatic go code and better encapsulate subscription and client handling into a dedicated package.

The Idea is to spawn multiple chat channels just by configuring channel name and websocket path in the routes.go file. The idea is to loop through a websocket config collection and using closure to initialize distinct instances for each configured channel, listening to redis messages on the subscribed channels.

This demo helped me a lot to set up chat server on heroku,
I had to extend to support multiple channels to make it work for my use case.

Hope my contribution helps some one who faced the same problem as me.

I know this is super old, but if you want to rebase and resolve conflicts I'd be happy to review.
