Added some guards against setting an invalid NKI.  It just happened!

The default reply from lookup_msg() is "Unknown NKI (this should not happen)"

If that does happen, it means that a number less than 1 or greater than
MESSAGE_NUM was given.  There may be something wacky going on with
Inform's random() function.
