DROPS 

Whenever you drop something, that thing's drop message is sent to you, 
if it has one.  If it has an odrop, then your name and the odrop 
message is sent to others in the room.  If the room has a drop-to, 
then the room's odrop will be activated when someone drops an object 
in the room.  Examples: '@odrop fish=tosses the fish onto the ground.' 
and '@odrop here=is whisked away by a cleaning robot that zips out of 
the wall.'
