Reintroduces separate contexts for users, channels, connections (now split into sessions and connections) and user-channel associations. It builds which is as much assurance as I can give about the stability of this commit, but its also the bare minimum of what i like to commit sooooo A lot of things still need to be broadcast through events throughout the application in order to keep states consistent but we'll cross that bridge when we get to it. I really need to stop using that phrase thingy, I'm overusing it.
