Mock authorization flow

[ferjm]

Authorization to 3rd party apps is outside of the scope of the prototype. However, we know that we don't want 3rd party apps asking users to enter their username & password (iif we finally use user&pass...), so we can at least mock an authorization flow where the user is redirected to the box to enter her credentials and we redirect the user back to the app with a fake auth token.

We finally decided to implement the login screen directly into fxbox/app so it's clear that authorization is not implemented at this point.
