Using python_requires to require Python 2.7 or 3.2+

This argument for setuptools uses the PEP440 version specifiers spec, so you can ask for:

python_requires=">=2.7,!=3.0.*,!=3.1.*"

The commas , are equivalent to logical and operator.

Note that the metadata generated is only respected by pip>=9.0.0 (Nov 2016).
