Reliable script to handle selection/drag-and-drop in a list field?

[Geoff Canyon]

Thanks for pointing out the new messages for behaviors. This
version<https://docs.google.com/file/d/0By_mW8YYOZpAOTE2blU1Y2JhMnM/>should
address the following:

 -- All messages should be "before" or "after" so they won't interfere with
your code.
 -- Clicking on the selection should not change the selection -- previously
if you clicked an item that was one of multiple highlighted lines, the
others would all be deselected, but then jump back if you dragged. Now the
selection remains, ready to be dragged.
 -- The image of the dragged items in most cases will be positioned as you
drag so that the spot you clicked -- whatever item that was -- should be
directly under the pointer where it was when you clicked to drag. This
doesn't do what I want when the dragged lines are more than will fit in the
visible list at one time. I'm still working on that.

Let me know what else you find.
