Brian Koropoff 687a0845b6 Introducing the GIB Object System (TM). This breaks scriptable HUD for now
and probably has enough bugs to leave the Orkin man scratching his head,
but it works and allows you to do neat things like write classes in GIB
(amazing!) and subclass builtin classes (which are Object and Thread at the
moment, Hash should be coming soon as a replacement for stem and leaf
variables).
