Alpha v7

The Grazr blog has been a little quiet as I've been testing a bunch of improvements to the current code base. I hope to start integrating the fixes today and continue introducing them over the next couple of days. Several of the fixes (including multi-grazrs) require a new include so I'm going to fork alpha versions 'pre 7' so that people's installs won't break. As I add the fixes, if anyone see's strange or broken behavior, please let me know!

I'll publish the list of fixes once they've been integrated
