Revision 439930

Added a MemoryPropertyEditor that allows you to specify memory sizes in the xbean config like: limit="20 MB"
Upgraded the xbean maven plugin to 2.6 and the new qdox that it used did not like some of our valid inline initialization of variables, so I had
to refactor to an equivalent form that qdox did like.
