Subject: - Added a check to prevent Blind from ending while standing on a fog
 of wall. - The mob Slave ai will be executed now even when the slave has a
 target. This will allow for "instant" warping to the master when it changes
 maps or teleports. if the slave has a target already, it won't unlock it and
 chase back to the master or anything like that. - Removed a couple of checks
 that prevents item ids above 20000. However, remember that the max id is
 still ~32k or the client is the one who's gonna crash!
