[Radiant] (yet another) sorting patch

[bodhi]

Hi All,

Sorry to step on your toes Erik, but I was halfway through this when 
you posted your patch (which I haven't had a chance to look at just 
yet). I converted the page list from tables to lists, and used 
scriptaculous to order pages. It doesnt do reparenting, so only allows 
you to sort children, not move children to different sections.

It's a pretty invasive patch, but I did get to remove most of the 
javascript from admin/pages/index.rhtml (I enjoy deleting code :) ). If 
anyone could take a look at it and see how it works for them, it would 
be much appreciated:

It breaks a few of the unit tests (due to the sorting) and I haven't 
tested it on Internet Explorer yet.
