Authorization

[crisptrutski]

Firebase supports

1: authorizing by a number of means
2. info on session (uid, how you authenticated, when session expires, etc)
3. terminating a session

Not interested in supporting all the auth mechanism to start, but can get far with just supporting anonymous and password based auth (and common to both platforms)

I'm currently building an application that will eventually use Google authentication and firebase, I'm happy to have a crack at Google auth support.

@tomisme thanks!

Adding some docs around auth using Matchbox would be great too (even though it's a pretty thin wrapper around the clients)
