Massive style cleanup

[Arcanemagus]

Adds a basic setup.cfg file with configurations for flake8 and pylama, fixes some basic issues with essentially every file including:

• Many, many, whitespace line cleanups
• Several unused variables and imports
• Missing coding and shabang lines
• Minor style fixes to more closely align with PEP8
• Turn print into function calls for Python 2/3 compat
• A few minor bugs
  • Things like using an undefined i in stream_limiter_ban_email.py
