Fixed stats page.  Also hard included the htcharts just to avoid rebuilding again.
Added some statistics, not yet complete.  Need to make sure awkwarded drinks have their action/related_id set properly.  Next year I'll look into why these are sometimes not properly set..
I think the stats are done, I'll need to uncomment the thing that fixes the badly recorded.
Merge branch 'master' of github.com:kheaactua/mayofest
