(svn r13422) [NoAI] -Change [API CHANGE]: remove Stop() as part of the AIController. This means you no longer need to have a Stop() function in your AI, nor is it ever called. This because it was silly, never used, and couldn't do anything real (all Sleep/DoCommands resulted in an assert, as the game expected the company to be gone).
