Bump ARel to 2.1.3

Asset urls master

  config.action_controller.default_asset_host_protocol

It's best to leave this unset.

When unset the :request protocol is used whenever it can be and
:relative is used in the other situations.

When set to :request then assets hosts will be disabled when there
is no request in scope and will use the request protocol whenever a
request is in scope.

If set to :relative, then a relative protocol is always used except
for stylesheet link tags which must use the :request protocol to
avoid double downloads in IE6&7.

Stylesheet link tags should use the request protocol to avoid duplicate download of stylesheets in IE7 and IE8.

Add asset_url helper and refactor the asset paths so that asset hosts can be used during asset precompilation.

with this variable without having to reference ActiveSupport::TestCase.
