fix(filmstrip): set SmallVideo styles instead of using animate
fix(filmstrip): set SmallVideo styles instead of using animate

jquery animate during animations sets an element's overflow to
hidden and then back to the overflow declared before the start
of the animation. If multiple animations are fired, then the
overflow could be set to hidden permanently. No calls
to Filmstrip#resizeThumbnails have animate set to true, so the
animate call is not even needed.
