[osg-submissions] bug fix in osgUtil::UpdateVisitor

[Robert Osfield]

Hi Gerben,

As Paul mentioned this isn't a bug, is very much a designed in feature
of the OSG's NodeVisitor.  It's is the responsibility of all Node
Callback to do the traversal of the node, there are a range of
benefits of this approach.  So please just add a travese() call into
your callback and it'll work.

Robert.
