Bug4764/s2 pagination

Updated to D's specs! Tested in FF18 on Linux by me (extensively, haha), and IE8 by Drew, both are functional. CSS compatibility means Chrome/Opera/Safari all should be good to go, though it's maybe worth a look. In IE7 it fails back to look like the current talkread pagination, and IE6 does the same though with bonus full-width background box because IE6.
