Add config.action_controller.include_all_helpers, by default it is set to true.

In older rails versions there was a way to use only helpers from
helper file corresponding to current controller and you could also
include all helpers by saying 'helper :all' in controller. This config
allows to return to older behavior by setting it to false.
