 * When a player aims at a teammate the plugin resolves the aimed entity with
 * get_user_aiming and, if it is a living teammate, shows that teammate's name,
 * health and armor in a small HUD refreshed a few times per second. Enemies are
 * never revealed, so the plugin gives no wallhack-style advantage.
