title: Drag & Drop Reorder Rows on NSTableView
body: <p>I was just wondering if there was an easy way to set an NSTableView to allow it to reorder its rows without writing any pasteboard code.  I only need it to be able to do this internally, within one table. I have no issue writing the pboard code, except that I'm fairly sure that I saw Interface Builder have a toggle for this somewhere / saw it working by default.  It certainly seems like a common enough task.</p>
  
  <p>Thanks</p>
