Added Download link to Nav Bar

I added a download link to the nav bar which just points to the OpenSUSE repo for now. It should probably point to a page that provides a bit more context, but for now I think it's good enough for now. I wanted to add a blog post while I was at it, but wasn't sure what to say :) So, I'll leave that until the time we can mention our updated docs. That said, we should probably say something about the new features in the 1.1 branch perhaps as one update we can do in the interim?
