title: UITableView disable "delete" confirmation
body: <p>This is similar to questions that are asking how to swipe/delete without confirmation:</p>

  <p>My tableview has cells with UITableViewCellEditingStyleDelete set.  When the tableview is in editing mode, the cells display a red circle icon with a '-' inside.  To delete the cell, the user taps the red circle, and a Delete button appears.  The user must then tap Delete which triggers <code>tableView:commitEditingStyle:forRowAtIndexPath:</code>.</p>
  
  <p>Some of my rows support UITableViewCellEditingStyleInsert.  In this scenario the cells display a green circle icon with a '+' inside.  Tapping the circle invokes <code>tableView:commitEditingStyle:forRowAtIndexPath:</code> immediately.</p>
  
  <p>I'd like to have <code>tableView:commitEditingStyle:forRowAtIndexPath:</code> invoked immediately when the user taps the initial red-circle icon.  That is, no delete-button step.</p>
  
  <p>Any ideas?  </p>
  
  <p>Is there a way to provide custom editing controls that slide in from the left like delete/insert?  If so, perhaps I could use this mechanism?</p>
