Make available funcs draggable.

[shlomif]

This is a proof-of-concept commit that makes #available draggable. It
uses the jQuery and jQueryUI CDNs and has some problems because there's
a lot of white regions above the #available which limits its visibility.

Thanks for the interesting idea. There are a couple of issues with this:

• In both Chrome and Firefox, the #available div disappears outside of the surrounding #controls div (I guess this is what you mean by "limits its visibility"
• In both browsers, when this is enabled, I cannot use the normal drag-and-drop of the functions anymore.
• I would really like to avoid pulling in jQuery and jQuery UI dependencies..

What was your initial motivation for this?
