When the lightbox is opened, or prev/next pressed, preloads the previous/next N images. Technical debt introduced: * initialization is a mess, with the viewer and the interface randomly setting properties on each other in different phases of execution. That got in the way and I shuffled things around until they worked, which is obviously not the way to have a robust system, but hopefully it will get scrapped soon anyway in favor of a clean top-down dependency injection.
