Flexible authentication solution for Rails with Warden.

Devise::Models::Authenticatable#valid_for_authentication?

Check if the current object is valid for authentication. This method and
find_for_authentication are the methods used in a Warden::Strategy to check
if a model should be signed in or not.

However, you should not overwrite this method, you should overwrite active_for_authentication?
and inactive_message instead.
