Index all old technical blog articles
I know that we're moving towards articles in our docs rather than technical blog posts, but it seems like we have a lot of technical blog posts out there that aren't included in http://docs.gitlab.com/ee/articles/. We sometimes link directly to them from other index pages, like http://docs.gitlab.com/ee/ci/README.html and http://docs.gitlab.com/ee/user/project/pages/index.html. Without moving the actual content, how about we put links to those old technical blog posts into the Articles index?
