Add option to load all streetview images at once
When working on a mission, it would be nice to be able to just load all relevant images at once, instead of having to press the
+-icon everytime to load more images.
Instead of just loading all images at once, trigger the "load more pictures"-action (i.e. the action when one presses the
+-icon) when the last loaded streetview image is displayed. Kind of like an endless scroll that loads more elements when one reaches the end.
