Laurent Bachelier 541d080c9d Use flake8 if available instead of pyflakes
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.

# XXX Currently, elementtidy segfaults when there are no error, because of

# A patch has been sent to Debian:

#
# As it is not integrated in Debian yet, and as this problem persists on other
# systems, using elementtidy is for now to avoid.
