This brings back the deprecated modules from ActionController, because
they didn't have any deprecation warning.

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.

Normally Rails.application is an instance, but for those
tests Rails.application needs to be class.

Previously, ActiveResource was using the connection level formatter for get requests. This made it impossible to use custom formatters per resource.

Additionally this commit makes the Connection request methods more consistent. It always returns a Response. The base will then decode it each the response using its format setting.

Merging this commit will allow users to add custom formatters on a per Resource basis. This enables handling pagination responses from the server side, a very common use case that was previously impossible without monkeypatching XmlFormat.

This commit updates new? so that it knows whether or not the record was actually new or not, and doesn't rely solely on the presence of id. This enables the ability to set a custom primary_key that is not autogenerated by the server.
