Do not exclude userscripts directory from pycodestyles
Do not exclude userscripts directory from pycodestyles

This directory is empty by default. Whether the user choses to put
codes in it that are PEP8 compliant or not is up to the user. So,
the choice of whether to exclude this directory from pycodestyles
should also be up to the user.

Additionally, do not exclude user-config.py from the flake8 checks
for the same reason.
