Test failures with Twill 1.8.0

[Ryan J Ollos]

As mentioned on the mailing list (​gdiscussion:trac-dev:sCRapSYsEGQ). After installing the dependencies of Twill 1.8.0: requests lxml and cssselect (​pull request #6 is needed to improve handling of the package dependencies), the first error encountered is:

$ python ./trac/tests/functional/__init__.py
Traceback (most recent call last):

Package versions are:

>>> import twill
>>> twill.__version__
'0.9'
>>> twill.__path__
['/home/user/Workspace/newtwill/py2.7/local/lib/python2.7/site-packages/twill-1.8.0-py2.7.egg/twill']
>>> import requests
>>> requests.__version__
'2.3.0'
>>> import lxml
>>> lxml.etree.LXML_VERSION
(3, 3, 5, 0)
>>> import cssselect
>>> cssselect.__version__
'0.9.1'

The version is in the Twill package on PyPI is incorrect. The version has been ​fixed in the codebase.
