Test failure under Python 2.7

[Tres Seaver]

Running zope.testing's own tests under Python 2.7 fails, because the unittest module
has been significanly refactored:

 $ svn co svn+ssh://svn.zope.org/repos/main/zope.testing/trunk zope.testing
 ...
 $ cd zope.testing
 $ /opt/Python-2.7.0/bin/python bootstrap.py
 ...
 $ bin/buildout
 ...
 $ bin/test --all

I made an unsuccessful stab at fixing this issue by replacing the
stdlib 'assertEqual' method with one defined locally on the testcase.
Maybe somebody else can use the attached patch as a starting point.

[Alex Smith (ajsmith)]

The tests have been fixed on the trunk as of r117136.
