Title: ActiveRecord agnosticism. Load fails on this line if AR has not been require'd.

Background: many people (like me) are using ActiveAdmin without ActiveRecord as ORM (I use Mongoid).

It should be possible to load AA without requiring AR first, however currently it chokes when trying to load the AA comments module. The solution is simply to skip the comments module for AR.
