Support configurable "User" models

[wireframe]

Devise allows for any model to be used as the authenticatable resource. Instead of hardcoding references to the User model, allow for configuration or inspect the devise config directly to infer the model to be used.

see:

• Devise.mappings
• Devise.authentication_keys

I think that would work best in the way the routes work with devise. You need a constraint to set the scope around the routes, which will allow you to access the scope mapping in the controllers through that parameter.
