Subject: [PATCH] AI freelook! I am no longer aware of any issues with it
 (other than one minor one involving it not removing the dim overlay
 sometimes, but that is very easy to ignore) If someone goes over the map and
 fixes the camera coverage, I suggest we force AIs to use this (and I'll be
 making a thread about it)
