@OSUCcess (object) [=(message)]
Sets the other success message for (object).
If no (message) is specified it erases any previously set (message).
Other-Success messages have similar purposes on different types of
objects. Typically, it tells the other players in the same room what
the player is doing:
ON ROOMS: It's shown to others in the room when a player enters or looks.
ON THINGS: It's shown to others in the room when picked it up.
ON EXITS: It's shown to others in the room when used it successfully.
If blank, "(name) (exit)s(name)" or "(name) goes (exitname)"
will show, depending on the exit type. (See AUTOS)
ON GROUPS: It's shown to the player that just lost membership.
ON PLAYERS: It's notifies a player they were just paged successfully.
On players, an @osuccess message is fairly pointless.
