Done.  I noted that we weren't making an owner dependency either :-(.

Also, we might want to think about letting stats objects be extension
members sometime.  As things stand, if an extension script does CREATE
STATISTICS, the stats object will just be "loose" rather than bound
into the extension.

We still have docs and nomenclature issues to work on.  Anyone want
to take point on those?
