Terry : Upgrade GitLab From 5.1 To 5.2

GitLab 5.2

Important Improvements

1. Forking
   You can a fork project into its own namespace now.
2. Code search
   You search inside the project with a search bar on top panel.
3. Turbolinks
   GitLab is much faster because almost all requests does not reload the page.
4. Shared deploy keys
   You can use a deploy key for as many projects as you need and one project can use multiple keys.
