Reviewers

This stuff can be reused in other pure serialization contexts (namely, webhook payloads), not only in HTTP responses.

This is an updated version of the review request at http://reviews.review-board.org/r/982, now using the github repository.
Ran ReviewBoard test suite with it, passed all tests.
