Decision made: traditional python setup for slink

[Gregor Hoffleit <flight@mathi.uni-heidelberg.de>]

Ok, now that I learned that the freeze is going to happen this Friday, 
it's clear that the time is too short to make the transition to my
experimental Python setup.

Tomorrow I will upload a new set of python packages, 1.5.1-5, with all 
official patches applied and a few new fixes included; there will be
no structural changes compared with the current 1.5.1-3.1, i.e. for
slink we will stick with /usr/lib/python1.5 etc.
