Note on COTD2's elevators: (VERY IMPORTANT!)
==========================================================================
   The elevators (outside the ones in MAP03) are BUG CITY!
In MAP01, if you repeatably hit the CALL switches, you can (and eventually
will) make elevators UNRETIEVABLE! LISTEN for elevators to STOP before you
hit the switch, if any are in use. Failure to follow this will render
elevators USELESS, and in some spots, elevators are the ONLY way to cont-
inue onward! SAVE before using them! 
   In MAP06, the Scriptless viriety is here, since Hager's scripted ones
somehow got lost, and are not retrievable. It is IMPROTANT to note that
fast switch hitting here will ruin the elevators, and sending them on
their way when running out of the car will make elevators UNRETRIEVABLE!
SAVE your game when using them!
   Chances for problems will not be likely in 1-player games, Multi and
Deathmatch may (and positively will) leave some players trapped. Remember
to SAVE OFTEN when using them!
   I got to figure out how to make a less efficient, yet BUG FREE, script
on my own (yeah, right)!
