Title: setup.py: Add clasifiers, long_description

setup.py can define metadata about the package. Some of it is
non-mandatory, but is useful for PyPi and elsewhere. As such, add a
long_description field (copied from current PyPi package, which was in
turn copied from the website) and a list of classifiers (based on the
current list on PyPi). Because we use the same setup.py file for both
Python 2 and 3, add a version check to determine which classifiers to
include.

This fixes issue 2615.

It should work, but I'm not exactly sure how to test this. @asmeurer?
