changed selection behavior as requested at

http://sourceforge.net/tracker/?func=detail&aid=2789933&group_id=222125&atid=1054680

file view - sidecars are added to the selection if they were expicitly selected
            or if the entry is collapsed
icon view - selection always contains sidecars

file operations splits partially selected groups - selected files have
disabled grouping
