Status: After the introduction of the selection widget the images are only autoselected (when choosing a registration) if no image was already set.
This differs from the old behavior, where a new registration always alters the images to the used images of the registration.

Should we change it back at least for the Evaluator? I think the new way could cost more than it brings, because I assume that when you select a registration you want to see the images that were used to determin this registration.
