Can't install on Python 3

[miguelgrinberg]

This package is currently registered as Python 2.7 only in PyPI. This is what happens if you try to install it on Python 3.6:

(venv) $ pip install lolviz
Collecting lolviz
  Using cached lolviz-1.2.tar.gz
lolviz requires Python '<3' but the running Python is 3.6.0

I think it's just a matter of adding the Python 3 classifier in setup.py, because as far as I can see the code is fine for Python 3.
