Generate special controller and functional test templates for http apps

The main goal is to not generate the format.html block in scaffold
controller, and to generate a different functional test as we don't rely
on redirects anymore, we should test for http responses.

In addition to that, the :edit action is removed from the http
controller and the edit route is not generated by default, as they
usually do not make sense in this scenario.
