GameModule.getUserId() is set in the preferences. I changed the plasce in
the code where it gets initialized.  It's now in
BasicModule.initIdentityPreferences().  The WelcomeWizard forces the user to
enter a non-null value, but it doesn't get invoked in edit mode.  That's
probably the cause.

I've checked in a change that ought to fix this.

Now I get an NPE in a different place when I try to load pre-3.0 saved games:

-- OS Linux
-- Java version 1.6.0
-- VASSAL version 3.0b1
-- Empires in Arms version 0.0

Can you send me the saved game and a link to the module?

I was able to load the current.sav file without error using the latest from
trunk.  Maybe it has to do with what side you had taken when you saved the
game.  However, I'm confused.  This stack trace is from loading the module,
not loading a saved game.
