Fix feedback view when retargeting the drop row & operation.
Fix feedback view when retargeting the drop row & operation.

CPTableView was inappropriately preserving the retargeted drop row & operation as the drag operation continued, causing the data source call to - tableView:validateDrop:proposedRow:proposedDropOperation: to echo any row and operation set by the first call to -setDropRow:dropOperation:, making it impossible for the data source to determine new values for -setDropRow:dropOperation:, making the feedback view stay in the same place it was initially drawn.
