Title: Add columns method to FbArray for select_all - Rails 4

The pluck method doesn't work because the 'columns' method isn't defined for the result object which is an FbArray.

The columns method is called at: https://github.com/rails/rails/blob/master/activerecord/lib/active_record/relation/calculations.rb#L154
