Coremob feedback baked into Ringmark

We've just pushed an update to rng.io that includes a bunch of changes that have been brought up in this group.  To see the details, check out the blog post at https://developers.facebook.com/html5/blog/post/2012/05/01/w3c-and-ringmark-updates/.

You can check out all of the changes to Ringmark in the changelog at http://rng.io/history/.

Also, Ringmark is now a part of Browserscope!  Thanks to Lindsey Simon and Steve Souders for making this happen.

As always, feedback is very welcome.

Thanks,
Matt
