Subject: [PATCH] playerdemos - recording actions of a player and playing them
 back using bots, to fake multiplayer demos. Still incomplete, and only works
 correctly with cl_movement 0 (otherwise you get minor changes on playback).

Cvars and commands for this have not really been made yet, and will come later.
