Killpack/auth *WIP* *WIP* *WIP*

WIP.

It's gonna work like this:
- You type in your username and password, which hits the `authorizations` endpoint. On successful authentication, it returns your auth token.
- Ember stores this auth token somewhere and uses it to make requests from thereon out.
¯\_(ツ)_/¯

In general, it's probably a bad idea to log things in production, but since we're so far away from a release, I thought it might be useful for debugging.
