[jdf-dev] Fork me on Github

Guys, Ricardo pointed out that we should make the "Fork me on GitHub" much more prominent for TicketMonster (he suggested the front page). To that end, I've added the Fork Me ribbon to the spotlights: http://www.jboss.org/jdf/stage/#3 Please review asap, and I'll push live if no objections. We can do a different colour ribbon if need be - info here https://github.com/blog/273-github-ribbons
