Bharat Mediratta 7ad0808a11 Change the API for getting to the original state of an ORM.
Old API:  $obj->original("field_name")
  New API:  $obj->original()->field_name

This allows us to revert the varous xxx_updated events back to passing
an original ORM as well as the the updated one.  This makes for a
cleaner event API.

  Old API:  comment_updated($comment) { $comment->original("field_name") }
  Old API:  comment_updated($old, $new) { $old->field_name }
