some svn movement

[Daniel Murphy]

If you don't have a checked out copy of jbox2d, you can ignore this announcement.

We've moved the working copy of jbox2d into trunk, and moved the old jbox2d branch into branches.  This might mess up your clients if you try to update.  To avoid mishaps, we're leaving the "updating" directory as it is, but please update your clients to point to trunk, as it will be removed soon.

Thanks,

Daniel
