[aprssig] ISS Tracking & Pass Information

Like I posted earlier, I'm monitoring all messages on the APRS-IS stream 
for ones addressed to a satellite.  I need to keep the message addressed 
very unique so as not to collide with other APRS users.

If I made you send the satellite name to a dedicated server name (say 
SATSRV), then I could make it respond to practically anything, but 
people would soon forget who to send the message to.  By making the 
addressee be the satellite name and the message content be anything you 
want, it'll be easier to remember which will hopefully make it get used 
more often and not die out over time.

And it'd be even longer to have to type a message to "SATSRV" just to be 
able to type "51" as the satellite name.  I'll take sending "x" to 
"AO51" vs sending "51" to "SATSRV" any day.

PS.  Remember, you must be in range of a bi-directional message gating 
IGate for this to work from a radio.  KD8QWT-7 just retried his request 
three times because he apparently wasn't getting my acks back.   And 
based on the 5 retries each of the three responses went through without 
an ack from him, I'd say he didn't get those either.
