Deprecate :controller and :action path parameters

Allowing :controller and :action values to be specified via the path
in config/routes.rb has been an underlying cause of a number of issues
in Rails that have resulted in security releases. In light of this it's
better that controllers and actions are explicitly whitelisted rather
than trying to blacklist or sanitize 'bad' values.
