Minified .js with http://yuilibrary.com/download/#yuicompressor

This is a better polished version of my original pull request, now removing all images from the lightbox and fixing remaining bugs some users of my gallery app found:

Hi there, I've written Panfolio to create photo galleries and thought about using OrangeBox for the lightbox effect, and as a pretty neat side effect have the sharing features in a per photo basis some users wanted, but it uses images for the loading effect and lightbox controls, as most of plug-ins out there.

This patch is not the prettiest I know, but I've never written any javascript before so... it does work fine to me. There's a live demo of my gallery app using OrangeBox at http://caio.ueberalles.net/panfolio-demo/

The choice for those unicode symbols was very particular, perhaps they could also be customizable through some options, I don't know. Anyway, I'd simply love to use your vanilla plug-in if you can merge this patch, otherwise I'll keep this mod to me!

Cheers :-)
