Title: add tox configuration file for easy testing

*[tox](http://tox.readthedocs.org/en/latest/)* is a useful tool that will create virtualenvs for each Python version and then run the tests in each one by simply running `tox`. I've added the configuration file to run it.

I find it useful, I leave it to you to decide wether to merge it.
