   idBot

   This is the in-game entity for a bot. This entity takes care of moving
   the bot through the world while the actual AI is implemented in idBotAI
   which runs in a separate thread.

  - QW:ET Bot. Begun July 5, 2006 
  - bot born in game (spawning in - but buggy, crashes) July 7, 2006
  - made thread safe (for the Xbox) August 8, 2006.
  - bot codename: Strogg Bot August 14, 2006.
  - medic class finshed: August 23, 2006.
