Title: please consider this patch to fix gh-85

...his allows barWidth to be rendered properly.

Note that Google's API now supports a 3rd param here, for space_between_bars:

chbh=
,,

(see http://code.google.com/apis/chart/image/docs/gallery/bar_charts.html#chbh)

I don't see how wicketstuff could support this without breaking existing code, as we'd have to modify IChartProvider to have a new method "getBarSpacing" or somesuch.
