[SQLObject] flake8 cleanness

[Oleg B. <ph...@ph...>]

Hello!

   With a few exceptions master branch is now flake8-clean (and hence
pep8-clean) for Python 2. flake8-cleanness for commits is now a
requirement. Please consider using pre-commit hook installed by running
   flake8 --install-hook
Don't forget though that older branches are still maintained but are not
flake8-clean.

Oleg.

           Programmers don't die, they just GOSUB without RETURN.
