Subject: Moved ActionMailer and ActionController railties options to inherited
 hook

This change is needed, because we must take namespace into account and if
controller's/mailer's class is namespaced, engine's paths should be set
instead of application's ones.

The nice side effect of this is removing unneeded logic in
ActionController::Base.inherited - now the helpers_path should be set
correctly even for engine's controllers, so helper(:all) will always
include correct helpers.
