Add calls to self.protocol("WM_DELETE_WINDOW", self.destroy) to the Tk

and Toplevel class constructors.  This means that if the window
manager closes the window, the Python-side Tkinter data structures
will be destroyed correctly.  (Most apps do this anyway, and it's
recommended practice; I see no reason why making it the default
behavior could be bad.)
