Officially drop support of Python 2.6, 3.1 and 3.2

These old versions are not supported anymore since February 2016 for 3.2
and October 2013 (!) for 2.6. It's becoming even hard to use and to
test, as more and more libraries and tools (flake8 for example) decide
to drop the support of these versions too.
