Enhancment suggestion: API ListGridField.setHoverWidth(int width)

Hi Isomorphic,

I just noted that I can't define the Tooltip/Hover item width per ListGridField, as it extends DataClass and I can't find a way to get to my generated Canvas for the ListGridField, neither from ListGridField nor from ListGrid.
I think it might be a good idea to add setHoverWidth (int width), as you already have setHoverCustomizer (HoverCustomizer hoverCustomizer)

Best regards,
Blama
