SYNOPSIS

    mapping Set(P_NOWAY_MSGS, mapping value)

      Modified via:
    void AddNowayMsg (string verb, string message)
    void AddNowayMsg (string * verbs, string message)
    void RemoveNowayMsg (string verb)
    void RemoveNowayMsg (string * verbs)

      /std/room expects also:
    string QueryNowayMsgs(string verb, string arg)

DESCRIPTION
    To allow more specific messages when a player tries to use a
    non-existant exit, this property stores for each direction verb
    the appropriate message in a mapping.
    During actual commands the property is queried through the
    QueryNowayMsg() function, which, in case that P_NOWAY_MSGS does
    not cover the actual verb, will return the default P_NOWAY_MSG
    (note the missing 'S' at the end).

EXAMPLE
      // Add two messages (the preferred form!)
    AddNowayMsg("north", "You don't dare to go there.\n");
    AddNowayMsg("west", "You bump into a wall.\n");

      // This is equivalent to the above.
    Set(P_NOWAY_MSGS, (["north" : "You don't dare to go there.\n"
                       , "west" : "You bump into a wall.\n"]) );

      // Set several directions at once.
    AddNowayMsg(({"north", "west"}), "You bump into a wall.\n");

      // Remove settings.
    RemoveNowayMsg(({"north", "west"}));
    RemoveNowayMsg("north");
    RemoveNowayMsg("west");
