djangoize content/units/<type_id>/<unit_id>

Suggestion: write a method decorator to do this part for you. Then every view can just return serializable types (strings, dictionaries, etc.) and let the decorator worry about JSONizing it and wrapping it in the HttpResponse.

This is obviously bigger than just this PR, but it will make every single view we have a little bit simpler, and also decorators are fun to write!
