Introduce nullptr and replace foreach with new C++11 range based for loops. Minor fixups of signals, file dialog usage. Apply the same changes to the ItemViews/puzzle example since it shares parts of the code with DragAndDrop/puzzle. Make some changes to both examples to that the diff of the two becomes small for easier comparison.
