bug#2238: 23.0.90; [PATCH] Regression in python.el

In Emacs 22, python-mode had an option, python-use-skeletons, which
controlled whether you would get a skeleton when you entered "def", or
the plain text.

This option is missing from Emacs 23 CVS, and I want the behavior
back, as I find the skeletons to be obnoxious and undesirable.

Patch is against current CVS HEAD.
