Travis pypy3 failure #318
Description
For once, it's not Travis fault, but setuptools: the latest setuptools version was pushed to Travis recently, and since then pypy3 is failing because setuptools does not support Python 3.0 - 3.2 anymore (and pypy3 stable is based on 3.2...):
/home/travis/virtualenv/python3.5.2/lib/python3.5/site-packages/virtualenv_support/pip-9.0.1-py2.py3-none-any.whl/pip/_vendor/pkg_resources/__init__.py:83: UserWarning: Support for Python 3.0-3.2 has been dropped. Future versions will fail here.
setuptools requires Python '>=2.6,!=3.0.*,!=3.1.*,!=3.2.*' but the running Python is 3.2.5

There is a pypy3 alpha based on Python 3.3, but it's still alpha so it does not support all features of Python 3.3, has performance regression issues and does not support Windows yet.
So we have two solutions:
- either we use pypy3.3-v5.2-alpha1 but it will be harder to reproduce and fix errors if they happen on Travis, and also the builds may take a lot more time to be done.
- either we somehow force Travis to use an older release of setuptools compatible with Python 3.2.
