Pause carousel when hovering over next and previous buttons

It's normal while mouse hover the clip but it's don't work with buttons.

Fix it just adding string (next to the line 100):
carousel.buttonNext.hover(pauseAuto, resumeAuto);
carousel.buttonPrev.hover(pauseAuto, resumeAuto);

after
carousel.clip.hover(pauseAuto, resumeAuto);
