Keep current Pic when adding files to PicViewer2

Try to get the position of the current picture after adding and clearing
the file list of PictureViewer2. While thinking of using std::find for
this I realized that the operator()-functions in Helper:: weren't used
any more, so remove them and the <algorithm> includes.
