DnD source prevent text selection when handles are being used.

[denovichas]

onSelectStart() in Container.js doesn't not check for the use of handles and stops the mouse click event from propagation to allows the selection of text for coping. The function should be;

onSelectStart: function(e){
   // summary:
   //    event processor for onselectevent and ondragevent
   // e: Event
   //    mouse event

   if(!this.withHandles && (!this.skipForm || !dnd.isFormElement(e))){
      e.stopPropagation();
      e.preventDefault();
   }
},

Backported to 1.9.x. If we need it earlier, we need a separate patch for earlier versions of Dojo. Thanks!
