Fix for QMTest to make it usable with python 2.4

[Stefan Seefeld]

The attached patch replaces references to the whrandom
module in QMTest by random, as is required to make
it usable with python 2.4.

I'm not exactly sure about side-effects of the change
applied to the 'DocumentTemplate' module. It seems
that file was imported from zope, and is only partially
used in the web frontend, so the change in that case
may have no effect at all (beside not producing
a warning any more).
