[Zope-Coders] Expanded tests

[Shane Hathaway]

Lest we become lax in unit testing ;-) I have expanded the nightly 
testing to include the 2.5 branch and Python 2.2 running the head.  Lots 
of tests currently fail with Python 2.2, so please excuse the big 
emails, but we need to take the opportunity to get any possible Python 
bugs fixed before a Python 2.2 final is released.

OTOH the test script has a slight chance of not working at all now. 
Please excuse that eventuality as well. ;-)
