Don't load Google visualization

[Paul Everitt]

ux2 still has:

<script src="http://localhost:6543/pg/static/r1333627739/ux2/google/jsapi.js" ></script>
        <script>
google.load("visualization", "1", {packages:["corechart"]});
</script>

Let's remove that. Radar, and certainly the bar charts, are not in scope any time soon.
