Remove flot, added highcharts, started converting

Only one chart is currently working, Years. Everything else is
commented out for now. Both jQuery and Highcharts are accessed remotely
(google for jQuery and highcharts directly.)
adjusted the html and head tags

html tag was missing, moved the links tags next to each other and fixed
the left-over temp name for the javascript.
more html5 cleanup in the head
Still a work in progress, but continuing to get highcharts in and working.
merge conflict.

git confuses me on a daily basis. It thinks i should delete all the
content of this file. Sure.
Merge pull request #8 from instanttim/highcharts

It's still a work in progress, but since the original author put up the project himself, I'm merging my branches.
