John Du Hart 8e3523c626 Followup r98500, conversion of the Javascript to use jQuery fully. It also makes the Javascript work outside of debug=1 (oops)
There's a couple of WTF moments in the code, this is really due to some issues with the PHP side of stuff. It really needs some TLC but for right now it works, I'll come back to it before 1.19 and clean it up.
