All callback from a widget into a module (e.g. for retrieving the status or the criticality state) now get a widget passed. This has the purpose of allowing a module to store state/widget specific data somewhere. This way, for instance, it is possible to store the interface name as part of the widget, thus making it possible to show the status of the correct interface.
