Deprecation warnings

[Rotonen]

If one bumps zope.testrunner to a new enough version, one sees these during test runs:

ftw.testbrowser-1.30.1-py2.7.egg/ftw/testbrowser/table.py:19: DeprecationWarning: NodeWrapper.normalized_text is deprecated in favor of NodeWrapper.text

ftw.testbrowser-1.30.1-py2.7.egg/ftw/testbrowser/widgets/sequence.py:102: DeprecationWarning: NodeWrapper.normalized_text is deprecated in favor of NodeWrapper.text

I've tried to bump zope.testrunner, but it has made time zones unstable for the requests driver in the tests.

That is probably a real issue, though.
