I'm adding some drag/drop capability for Bug 30079, which ends up needing to be
able to drag TreeOutline elements.  Ideally, you could add drag listeners on a
tree container, and then the listener applies to the children as well.  More
efficient than having to add drag listeners to each child.  This doesn't seem
to be easy to do (adding a listener to the parent), for various reasons, in the
current code path.  It would be much easier if TreeOutline had built-in support
for this.

Additionally, because so much of the Web Inspector UI is built with
TreeOutline, enabling some of the drag/drop behavior in TreeOutline itself
seems like it should make it easier to make a LOT of stuff more easily drag-
and drop-able.

What I'd like to do first is collect some use cases for things we want to
drag/drop support for, that exist today in a TreeOutline.  We can then figure
out what kind of shape we want the API to be.
