Alien (BUGFIX 1.7): Routine at 38903

The two Trackers (items 6/7) and the carried cat ("Cat in Net"/"Cat in Box", items 20/21) are motion detectors: for each one held in a FRONT hand (marker >= 160), TrackerHolderRoom sweeps the rooms adjacent to the holder and fills the matching NearRoomList entry (33692: tracker #1, tracker #2, the cat) with:

the holder's room if nothing moves next door ("all clear" — worth +1 morale to everyone standing there, 36283)
or 255 if something does (which makes the viewed holder's tracker beep, or Jones grow uneasy — ViewedTrackerCheck)

Used by the routine at 38379.
