Preferences: Add default implementation for filtering

The default "matches" method now takes the widget and looks for all
child labels, checkboxes, push buttons and group boxes.
Because of that, the former "createWidget" method
can be called multiple times without creating a new widget
(-->widget()), and the "finished" method must ensure that the created
widget gets deleted, since not all widgets that were created are added
to the UI anymore.
