Update slim for sidekiq dash
Upon login reset the default ember headers
Set Authorization in the default ember headers
Remove stale comments
Stub out properly (since some users will be able to delegate authority)
Allow the auth token to do the heavy lifting for us. If producers were only owned by one user this would seem a little strange, since it would normally be /user/:id/producer and then either return a 401 or the information itself, but since users may one day delegate authority to another (especially in the case of a corporation-user, ala github) we'll stub it out like this for now
