net_dead - called by the MudOS driver when an interactive object drops
void net_dead( void );
If an interactive object (i.e. the player object) suddenly loses its
connection (i.e. it goes "net dead"), then the driver calls this func‐
tion on that object giving it a chance to clean up, notify its environ‐
ment etc. Be aware that functions that depend on the object being
interactive will not work as expected.
