Python 3 issues

tox.ini is configured to run flake8 tests on Python 2 but not on Python 3.

flake8 testing of https://github.com/IBM/pyxcli on Python 3.6.1

I have fixed the compatibility issues with PR #9

@wegotthekeys Those fixes work great for Python 3 but unfortunately they can break Python 2 in the process like if you have a real unicode string like u"Lüsai" or a real long like 1L.

Try something like this to define the legacy terms in the new language:

try:
    long        # Python 2
except NameError:
    long = int  # Python 3

try:
    basestring            # Python 2
except NameError:
    basestring = (str, )  # Python 3

By the way... I spent a decade living in Rochester, NY... A great place to live!

Hey @cclauss thanks for that information; I didn't even think of it :) I used the code from your PR #5 to apply that fix.

Also very interesting that you know of this place and have lived here! I'ts nice to hear that.
