[aprssig] qAR & qAr, same igate

Do you have multiple feeds for your IGate into APRS-IS?  If so, change
to a single feed.

I am not aware of which server software inserts an asterisk in the q
paths.  The software that is doing this is mangling the q construct.  I
would guess that since that software is also reinserting the packet with
the qAr construct, somebody has some bad server software out there that
isn't even dupe checking properly.
