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.

There were actually 2 problems with this one:
* script_name was added to options as a string and then it was used
  in RouteSet#url_for with usage of <<, which was changing the original
  script_name
* the second issue was with _with_routes method. It was called in RoutesProxy
  to modify _routes in view_context, but url_helpers in views is just delegating
  it to controller, so another _with_routes call is needed there

Include application's helpers and router helpers by default, but include engine's ones for controllers inside isolated namespace

It's based specifying application's script_name with:
Rails.application.default_url_options = {:script_name => "/foo"}

default_url_options method is delegated to routes. If router
used to generate url differs from the router passed via env
it always overwrites :script_name with this value.
