Add Python3.4 compatibility

[raulcd]

Compatibility for Python3 to strategypy. ./play.sh currently works for both python2 and python3 with this changes Currently tox passes tests on both python2 and 3:

Support for consolefe.py added. See below the output with python3:

(strategypy3)raulcd@strategypy (feature/python3_compatibility)* $ strategypy davide happiness | python strategypy/consolefe.py
Player davide won in 70 turns
Initial unit count: 20
Final unit count: 9
Player happiness killed: davide x 1,
Player davide killed: happiness x 10,
Player happiness was killed by: davide x 10,
Player davide was killed by: happiness x 1,
(strategypy3)raulcd@strategypy (feature/python3_compatibility)* $

Also tested with Python2

Looks good. A couple of minor things:

• README file should be updated, so that we specify that strategypy works on both py27 and py34
• setup.py should be updated, to include py34 in the classifiers (https://github.com/davide-ceretti/strategypy/blob/master/setup.py#L45)
• setup.py should be updated, to include six as a requirement (https://github.com/davide-ceretti/strategypy/blob/master/setup.py#L18)

@davide-ceretti I've added on the last commit this minor changes. I can expand on the README if you want but I suppose indicating that system dependencies are python2.7 or python3.4 is enough. Let me know if you want me to expand on it.
