Self-terminate 'float' after widget instance

[cubiclesoft]

This widget applies a 'float: left;' style to the elements it creates but then doesn't clear the style afterwards. This causes problems if the widget doesn't occupy 100% of the available width - specifically, other elements on the page start floating around it. In my specific use-case, I can clear the float after the widget instance, but that may not always be a viable solution.
