Title: Added check for already hidden elements

Fix for #128

It is just needed for fadeOut elements, as for fadeIn it seems to work flawless, even on subsequent calls to fadeIn.

I think the place seems right, as we won't have called the whole cssCallback magic. It adds a bit stress though, because we need to encapsulate the DOM element inside jQuery to check for ':hidden'
