[readme?] Problem when user class has different name than User

[piotaixr]

Version: 0.3.4

My user class is sth like BlahUser.
Configuration:

PolicyManager::Config.setup do |c|
  c.user_resource = BlahUser # defaults to User
  c.admin_user_resource = BlahUser # defaults to User
  [...]
end

When i visit /policies/user_portability_requests, i have an error saying that PortabilityRequests does not have a field blah_user_id. I had to change the migration CreatePolicyManagerPortabilityRequests by hand (rename user_id to blah_user_id).

Is it the expected behavior or am I missing sth? (or the Readme?)
