1) We now use __call() in REST_Controller to handle any requests to a controller that were not already handled. In the case of RESTful controllers, this should be the only entry point (although they're free to break the model and add other ones.. nothing stops them). This means that we can remove all the catch-all routes in routes.php which greatly simplifies it. 2) Move request_method() and output_format() out of REST_Controller and into the REST helper in core/helpers/rest.php 3) Experiment with letting the various subclasses check the output_format and deal with it themselves. This simplifies the API, but it might be a bad idea in that it might push too much work to the individual controllers. It's a balancing act, time will tell, I'm willing to change it back later.
