A real fix for the problem where:
import random
would result in every call to random() returning the same value
in the web interface.
While cgi/client.py:Client::__init.py__ was calling random.seed(),
on most systems random was SystemRandom and not the default random.
As a result the random as you would get from:
import random
was never being seeded. I added a function to access and seed the
random bound instance of random.Random that is called during init.
This fixes all three places where I saw the broken randomness.
It should also fix:
http://psf.upfronthosting.co.za/roundup/meta/issue644
I also removed the prior code that would bail if systemRandom was not
available.
