! Fixed a couple of bugs that screwed up the scroll position for very large select boxes (again: think timezone selector), in at least one specific situation: opening the dropdown below the select box, closing it, then scrolling up and reopening the dropdown above the select box (or the other way around.) This fix costs about 30 gzipped bytes, for something no one will ever notice, but when it comes to sbox, I'm a perfectionist. (sbox.js)

! Also fixed center positioning of currently selected select box item when reopening the select box in the same fashion. Costs another 10 bytes or so... (sbox.js)
