This reverts commit a288b74f.

Extracted localized_cache.rb from ActionController, added it to AbstractController and made ActionMailer use it.

Move all render and layout pieces required in ActionMailer from ActionController to AbstractController.

abstract all of the ActionMailer delivery methods into their own classes. thereby the following are equivalent

  ActionMailer::Base.delivery_method = :smtp
  ActionMailer::Base.delivery_method = ActionMailer::DeliveryMethod::Smtp

we could equally set our own custom object
as long as it provides the instance method :perform_delivery(mail)

eg.

  class MySmsDeliveryMethod
    def perform_delivery(mail)
      Sms.send(mail['to'], mail['body'])
    end
  end

  MySmsMailer.delivery_method = MySmsDeliveryMethod.new

Change Event#thread_id to #transaction_id. Defaults to one "transaction" per thread but you can explicitly declare the start of a new one. This makes it possible for each request to have it own id.

AS::Notifications.subscribe blocks are now yielded the arguments to pass to AS::Notifications::Event.new
