Detachable tabs in the new Debugger

I'm really loving the new debugger interface, with the
dockable/detachable panels being able to float, or be tabs etc. and was
wondering how we can reuse that in our own plugins?

Primarily I was wanting to see how well the TestNG plugin would look if
I switch to using that so we could drag the test result tree to a tab,
which would might work nicely for those who wish to attach the
run/debug windows to the sides of their screens rather than the bottom.



(I'm also wondering how well that framework would work for the editor
itself - detachable edit windows anyone????)
