Improve code style with flake8

- We agreed on 100 columns time ago, so I move around a few things,
- Removing unused modules,
- Fix white-spaces tabs without being multiple of 4,
- Encourage the use of os.path.join when joining paths,
- Using .format() for string formatting,
- Remove white-spaces from default arguments,
- Adjusting white-spaces before inline comments,
- Adding extra newlines when expected,
- Adjust spaces for lines under-indented for visual indent,
- Remove white-spaces from parenthesis, and adding them for arithmetic operators.
