Title: Firefox support enabled for Impress.js

I think my additions is minimal to you original superb code. :)

I made small change in the CSS files as well. As it turns out, Firefox is not good at all when animation semi-transparent elements. Therefore, I set the opacity value of non-active steps to zero. This makes the animations very smooth(er).

Best regards,
