OpenID support

Note that I had to downgrade Flask to 0.9 to fix an issue with flask-login. More on that here: http://stackoverflow.com/questions/17092849/flask-login-typeerror-decoding-unicode-is-not-supported, t\\e dev server has a corrected environment.

You'll notice that I'm embedding the user JSON in your index.html template: http://cl.ly/image/1O231W2t3c2T, I'm then loading that JSON and putting it on angular's ```$rootScope```. That means that you should be able to access the user object in any controller by ```$scope.user```

I didn't do any other client side work. I'll leave that up to you, or another night for me :)
