Comment 3 for bug 1275581

Decided to take the plunge and upgrade the jQuery to v 2.1.1 (latest stable) and jQuery-ui to 1.10.2 (latest stable that doesn't break draggable helper function positioning) to see what prolems occur.

Needed to add a deprecated_jquery.js file to handle a few things for IE8 - which can be removed when we don't need to worry about that anymore.
