title: Keep QTableView scrolling to the last row when the model is growing
body: <p>I've a QTableView in a pyqt application. I continuously append rows to the underlying model. And what I want is the view to continuously scroll to the last, most recent row (is that behavior called "autoscrolling"?). But instead, the view does not scroll at all (automatically) and stays at its position.</p>
  
  <p>Can I enable this autoscrolling behavior somehow or do I need to code something to achieve it?</p>
  
  <p>Cheers,
  Wolfgang</p>
