Press kit for GitLab flow

Originally was a blog post proposal, but this should be done internally.

mentioned in issue blog-posts#71 (closed)

@nearlythere I think the press kit should be added to http://doc.gitlab.com/ee/workflow/gitlab_flow.html

@amara do you know what is this about?

No I am not familiar. This was before my time. But the press usually doesn't ask us for this.
