FW: add spacers to Traditional Toggles.

Scrollable toggles merge also included adding backgrounds to
traditional toggles.  on rows that didn't have 6 Toggles,
those backgrounds would be stretched.  This adds
spacers on the ends of the last row to force the toggles/
backgrounds to keep the proper size/shape.
