Berthold Stoeger 9efb56e2d4 Dive pictures: don't update all images on drag&drop to profile
Gracefully handle drag & drop to the profile, which changes the
offset of the pictures. To do this, keep the pictures in the
DivePictureModel and the ProfileWidget2 sorted by offset and
re-arrange if needed to keep the list sorted. This needs some
code reshuffling.

Introduce a helper-function that moves ranges in arrays.
