Wrap the zope testrunner for ZODB in something that can be invoked using "setup.py test".  The ultimate result is:

  Ran 2510 tests in 629.115s

  OK

Although when I do:

  python bootstrap.py
  bin/buildout
  bin/test

I get:

  Ran 2821 tests with 0 failures and 0 errors in 6 minutes 55.513 seconds.

I'm not entirely sure how to account for the difference in # of tests yet.
