Feature/update workflow

Hello Kim,
I've talked with Vladimir in Skype and he told me he has delegated the docopt.c project to you. I've also talked with him 3 months ago about some changes I was thinking about doing and now I've finally finished them (https://github.com/docopt/docopt.c/pull/1)

Tell me what you think about this changes

[EDIT] I see you've changed some things in `docopt.c.py`, maybe its better if I fork your repo and apply my changes to it?
