Convert RB.ReviewReply to Backbone. This is another relatively simple conversion for the data model for ReviewReply objects to be based on BaseResource.
Replied to an existing review with body_top, body_bottom, and children CommentReply objects. Published that reply and saw it get saved correctly. Verified that loading a draft reply worked as expected. Ran js-tests.
