On deletion of a single or multiple pictures, the whole DivePictureModel was repopulated, which was clearly visible in the UI, owing to the reconstructing of all images in the profile plot. To avoid this vexing behavior, implement proper deletion routines in DivePictureModel and ProfileWidget2. Since this needs sensible erase() semantics the QList<PictureEntry> member of DivePictureModel was replaced by a QVector. A QVector should be the default anyway, unless there are very specific reasons to use a QList (which actually is a deque, not a classical linked list).
