Add --enable-extensions flag to Flake8

Browse source 
This new flag is added so that off-by-default extensions can be enabled
without using --select which (currently) causes several problems with
pep8's rule engine. This also adds support to the --enable-extensions
flag to be specified as a multi-line config option in an appropriate
config file.

Closes GitLab #67
