Dev Ops: Auto-update packagist

[mariacha]

This needs to be set up by someone who has admin access to this repo, and can look at: https://packagist.org/profile/

There's information about it here: https://packagist.org/about#how-to-update-packages

I might need to add you to the package to make it all work: https://packagist.org/packages/united-philanthropy-forum/km-starter-kit

• [x] TODO here is to update the starter kit to use v0.1.0 instead of dev-master.
