I ported over the code to use the Koala library instead of Mogli. You can see this code running here: https://sharp-dusk-7286.herokuapp.com/
I also added a convenience sign out url https://sharp-dusk-7286.herokuapp.com/sign_out for testing purposes.
Let me know if you have any problems
initial port from mogli to koala
Looks great to me!
Do we have green lights from Morten to merge/deploy?
Yes, this looks good to me. I would merge but please DO NOT DEPLOY to production before I've QA'ed with Facebook.
Cool, just let me know when to deploy.
