[Biopython-dev] No longer testing under Python 3.1

[Peter Cock]

Hi all,

In line with past discussion, we're not officially
supporting Python 3.0, 3.1 or 3.2 - just 3.3 onwards.

Until recently the Buildbot has been covering
Python 3.1 and 3.2, but as of this commit I have
dropped Python 3.1 from the test matrix:

https://github.com/biopython/biopython/commit/de71aadb8c603a6cd30b563fe7bc44d56b98d506
http://testing.open-bio.org/biopython/tgrid

For now everything seems to work under Python 3.2
(testing under TravisCI and the buildbot) which may
be useful as PyPy3 currently targets Python 3.2
rather than 3.3.
