Title: Use the auth_key specified in the model instead of the hardcoded "auth_key" string

This patch enables using only email/username fields instead of auth_key
in the registration/login forms (as spotted in
http://asciicasts.com/episodes/304-omniauth-identity).

With it omniauth-identity integration becomes a bit easier.
