protect protected branched to force updates
requested to merge github/fork/Popl7/add-better-branch-protection-against-history-rewrite-and-deletion into master
Created by: Popl7
this is a first (working) setup. There are changes to the api call from gitlab-shell. I will post a PR for this as well. (#128 https://github.com/gitlabhq/gitlab-shell/pull/128)
Tests must be made.
