Patch is synchronized with tip. It also removes Studbutton and Tributton classes which depend on removed methods. These classes are not documented, not tested and never worked in supported Python versions. I even not found reasonable links in Google, except an annotation [1] and autogenerated from Tkinter sources docs.

I now think that perhaps we should apply this patch to 2.7 and 3.4 too. Non-working (and non-worked last 10 or 15 or more years) code only confuses people.
