Title: fixes #750 - load hooks return ActiveRecord::Model in Rails 4, use Concern

@ryanb -- this seems to fix the load issue when running under Rails 4. Tests are passing. But should this be approached differently, specifically, should we be adding `accessible_by` to `ActiveRecord::Model` instead of `Base`?
