Selection: count duplicates and removals from the step's own picks

The count line now uses the objects the selection step itself picked
(a click, a window or crossing, a lasso, a fence, Last / Previous /
All): "N found (D duplicate), M total" when some were chosen already,
"N found, R removed, M total" in remove mode, "N found, M total" when a
removal picks objects that were not chosen.
