With flake8, we can check for more issues and ignore those who are not
real issues.
This allowed me to find genuine errors in:
- modules/boursorama/pages/account_history.py
- modules/ing/pages/login.py
- weboob/tools/application/qt/qt.py
I left one in weboob/tools/browser/browser.py for the time being.
Some PEP8 fixes on other files.
FIP now uses the same website as most Radio France radios.
As a consequence, it is able to support CapVideo.
There are a few differences between FIP and the other radios, but this
still allowed for less code, and the code should be more robust for
every radio.
