BColumnListView: Enable invalidating rows, fix SetField()

Browse Source 
* Seems like there was no easy way to simply invalidate
   a given BRow. Introduced BColumnListView::InvalidateRow().
 * BRow::SetField() tried to invalidate the row, but invalidated
   the listview instead of the BOutlineView responsible for
   drawing the list contents. Use the new InvaalidateRow().
