2014.11.04 MSS Code Factory 1.11.12534 Added PostgreSQL sp_movedown_dbtablename

The stored procedure sp_movedown_dbtablename has been created and
test installed for PostgreSQL, but not actually run.

Next I need to take a step back from the PostgreSQL code, and implement
the Chain functionality for the RAM storage.  During that implementation,
I'll be defining the new JDBC table interface methods and adding
Not Implemented Yet stubs to the various database JDBC layers.

I will not be testing the new moveup/movedown functionality using the
RAM implementation, however.  As long as it clean compiles, I'm going
to assume that it'll work for now, because I don't want to create a GUI
that runs a SAX loader to populate a RAM instance for subsequent manipulation
by the GUI.  Someday I'll do something like that as an editor for Business
Application Models for those who prefer flat-file storage to using a
database, but that's very far down the road.
