Title: Remove deprecated action lookup as methods on controller.

The older lookup in the root of the controller has been deprecated
since late-2013, and is a frequent cause of annoyance for newcomers.
This PR removes the deprecated lookup completely.

This removal has been discussed and approved by the full core team.
