no idea what I changed b/c it was last week
a few debug attempts for update controller/test
Issue #26 Add News service and controller

* Add `{id: '@id'}` to the service resource definition so the 'id' param
  ('@id') on a passed model will be mapped to the ':id' in the API url.
* Fix some test fixtures to use 'id' instead of '_id' so they use the
  previously mentioned mapping
* Update some test expectations to hit the appropriate urls
