JSONP was specified as a output format causing documentation problems.
Created by: andrewyatz
Problem raised by a reviewer. Branch has been made against b3aec9dd so it can be cleanly applied against master and release/76.
We specified jsonp as an output format. This caused problems in the documentation code which looked to see if JSONP was already specified as an output format. It meant that callback was not added as a parameter which is a bit poor. Removing jsonp as an output format fixes the error.
