Listview S9

[Dimitrie O. Paun]

This fixes some focus problems.

ChangeLog
  Instrument SetItemT to change only _one_ item at a time.
  That is, if we have to change focus, we call it recursively
  to first remove the focus from the item that has it.
  This allows simpler, and more correct invalidation handling.
