Red Hat tab dropdown support and updated bootstrap-community theme references

Hi,

All project sites need to have Red Hat logo in the footer and Red Hat tab dropdown in the right upper corner. We've introduced the second feature in bootstrap-community in recent releases therefore I created a simple pull request which updates references on your site to the newest version of our resources and uses our newest main project.html.haml layout file. I looked around the site and everything seems to be working fine after the change but please double check.
