2014.07.18 MSS Code Factory 1.11.12272 Request/Response implementation of LogIn/LogOut coded

That's it for the messaging layers and the core Java layer enhancements
in order to support client-server and distributed logins in a very insecure
and pointless fashion.  But it will serve it's purpose of letting me log in
through the GUI, log out of it, and access the database objects in between
so I can start populating the windows with data.

Next up: wiring the new methods to the Swing GUI login/logout code,
and dynamically adjusting the menu item permissions accordingly.  Maybe
I'll even auto-close all the JInternalFrames when you log out.  I should.
