Delete an accidentally checked-in feature that actually broke more

than was worth it: when deleting a canvas item, it would try to
automatically delete the bindings for that item.  Since there's
nothing that says you can't reuse the tag and still have the bindings,
this is not correct.  Also, it broke at least one demo
(Demo/tkinter/matt/rubber-band-box-demo-1.py).
