ComplianceControlDecorator: Convert to new action links interface

* Decorate the `ComplianceControl` so we can show the action links from
  the decorator in the header.
* Add a `decorates` to get `object_class` to work inside the decorator.
* Define `AF83::Decorator.define_instance_class_method` in order to
  enable the `@compliance_control.class.METHOD` calls in the view to
  work. Thanks very much to Johan for figuring out a way to do that.
