This cleans up the last bits of deprecation stuff from form_for helper.
However there is still a bug when using :as => foo[], with index. The
classes and ids are being generated using [], such as foo[]_edit. This
bug already existed but it was not detected before.

This removes all deprecated classes in ActionController related to
Routing, Abstract Request/Response and Integration/IntegrationTest.
All tests and docs were changed to ActionDispatch instead of ActionController.
