working on chat in hapi-chat

In regards to https://github.com/dwyl/apprenticeship/issues/8 @finnhodgkin and I are going to work on building a chat in a component style.

Because we are not familiar enough with Elixir we don't feel comfortable doing this with the backend that is currently in place so we are going to do it in a staging branch on https://github.com/dwyl/hapi-socketio-redis-chat-example so that we can play with the back end (since it is a server we are familiar with).

We also do not have push access to this repo so doing it in the hapi chat repo makes more sense for now.

Please let us know if you want us to move it or what is preferable.
