Actually deals with the problem by ignoring it completely.
No authentication is done.  Anyone can log in with any name and more
than one user can have the same name at once (just like Life, eh?)
There's just a stub called loginUser() that anyone can override for
system-specific implementations.  It was mainly to let me log in with
multiple users so I could see how they interact with one another.

It's this way because I'm not sure what (if any) sort of object-
persistance architecture is envisioned for TR.  Some sort of file-based
database (like Cold or LPC, which I currently prefer) or a large
monolithic db (like the venerable LambdaMOO or maybe pickling the
entire world) or a relational-database-backed db (although I don't quite
understand why anyone would want to do this) or what-not-and-not.

Anyhow, my patch is attached.

Eric
