Google charts

This branch has a working prototype of the Google chart. A couple things to keep in mind is that it wasn't possible to do things in an external JS file. Google charts just don't work unless it's inline with the HTML. See the below link for some more details:

Not ideal. Still, to keep things sane I set it up in it's own view script. 

That said, this should definitely be tested by some of those Stash users who had a problem. The big reason is that the Tooltips in the chart uses the debug data so it'd be nice to confirm they're usable with raw HTML displayed. For me, and my setup (and how I build sites), no issues and it worked lovely though. 

Let me know what you think.
