Code cleanup and automated PEP8 code style check (flake8)

[pax0r]

Partially solves #52

Mostly automatic code recaftor, but should help you keep with PEP8

Thank-you! I'll resolve conflicts for you shortly and merge.

Actually, if you don't mind @pax0r - could you resolve the conflicts here? If you compare to master you can see the folder structure change that broke this pull request. I'll continue to tackle #61 in the meantime.

I did it - FYI read https://www.python.org/dev/peps/pep-0008/ for better Python-like code style :) you can use tool flake8 (http://flake8.pycqa.org/en/latest/) to test code-style on your local machine too. Simply install flake8 with pip and run flake8 command in your project directory. Welcome to the wonderful world of Python :)

Thank-you. I am familiar with pep8 / python quite well, this is an old project of mine that's slowly getting a refactor (you can see better examples of this in https://github.com/codingo/vhostscan). Merging this over now but will likely replace these test cases in the future to mirror that of other projects of mine for consistency.
