[MRG] A tool I use to quickly check pep8 on MPs.

A few people have asked what tool I use, so I though I would put it up here.

The command I use is:
./checkout-flake8.sh lp:launchpad_openerp_repo module_name
for example:
./checkout-flake8.sh lp:~savoirfairelinux-openerp/partner-contact-management/user-firstname/+merge/210710 partner_firstname

It checks it out in /tmp and runs flake8 on the module
