Merry Christmas to the server CPUs. It occurred to me that we could

accomplish our "previous value" support in the distributed object system
without using reflection and could also avoid using reflection in the case
where we have already applied the event on the server (which is generally
the case on the server).

Rather than hacking up the gendobj script, I took this opportunity also to
rewrite the DObject generation script as an Ant task and in doing so,
implemented another recent idea which is that we can just augment the
FooObject.java file instead of having a separate .dobj and .java file.

You'd think it was spring there's so much cleaning going on.
