Fixed requirements handling.

Do not depend on pip internal parsing of requirements.txt, reference
setup.py from requirements instead. Same for requirements_dev.txt, but
now use the extras_require and reference the 'testing' feature
dependencies.

The builds will fail to due valid flake8 problems. Anyome is welcomed to solve some of them as I will not make a new release before they are all fixed.
