SYNOPSIS
        void catch_tell(string)

DESCRIPTION
        When a message is sent to an non-interactive object, via say(),
        tell_object, tell_room() or write(), it will get to the function
        catch_tell(string). The idea is to enable communications between
        NPCs and from a user to an NPC.

        Messages sent to an interactive object are also passed to that
        object's catch_tell() lfun, _if it has one_. If the receiver
        (or one of its shadows) doesn't have that lfun, the text is sent
        to the socket directly. Only messages sent by an interactive
        object to itself is always written to the socket immediately.

        This allows to filter and process text before it is written
        to a player.
