Lack of interest Moving light-box imagery

[Shelley]

I'm sure there's a good reason unknown to me but suggesting for the lightbox-sprite.png imagery to be moved into the xenforo-ui-sprite.png.

I think the reasoning behind this is the lightbox images will be loaded far less than the others which is why they have been kept separate.
The sprite has been expanded to include the arrows though: http://xenforo.com/community/styles/default/xenforo/widgets/lightbox-sprite.png
