Certain objects can be hung on walls, mainly paintings, signs and
others which serve decorative purposes. Objects that have been hung
become part of the room description and no longer appear with more
obvious objects noticed in the location when you LOOK at a room.
Additionally, objects that have been hung up cannot be gotten as easily,
as they must be unhung from the wall first.
To hang up a decorative item up, use HANG <object>.
To remove it from the wall, use UNHANG <object>.
Note, HANG can only be used in locations with walls. Typically
if a room is considered to be "indoors", it will be suitable to hang
objects in.
Syntax:
HANG <object>
UNHANG <object>
