Ok, it's definitely going in, I was originally thinking about being cheap
and leaving it as an aside whilst I built tabpane up around selectable and
focusable.

But we don't wanna do that... :P

So I'm abstracting it out into 'draggable'.  The lib.abstract version of
draggable is the very simple code I posted earlier; where somthing is
interested in 'on release only' dragndrop items.

The lib code will be for those interested in 'as you drag' like the tabs and
reordering, or the reordering of columns in table, or the reordering of
icons, for example.

Btw, I was *very* impressed with the dragndrop code you wrote for tabpane.
It uses some very clever workarounds for getting mouse coords.  Did it work
on all the platforms you tested it on?
