Updated links to the newest bootstrap-community release and corrected Tabzilla styling.

Pull request related to https://issues.jboss.org/browse/ORG-1871

In project.html.haml layout I've only added a wrapping div so that styles created by Cheyenne can work correctly but due to indenting whole file content looks like modified ;).

You may also want to switch back to using bootstrap-community.js from static.jboss.org rather than your own built one but I didn't make this change in site.yml since you might have some other customizations that I'm not aware of.
