Better handling of the REST API plumbing.

* Add a version_info field which is a better way to do ordered
  comparisions of the API version.
* All subresources now get their .api attribute set automatically, if
  they are passed back through the ObjectRouter.  No more fiddling with
  context['api'] (unless of course, they don't make a roundtrip through
  the main ObjectRouter loop.
