[ACTIVEMODEL] Added injection of the `paginate` method when missing (Kaminari)
[ACTIVEMODEL] Added injection of the `paginate` method when missing (Kaminari)

The `paginate` method, needed for the import task, is injected in the class being imported
when the class implements Kaminari pagination, so the import Rake task works out of the box.

Closes #191. Also see: #48, #108.
