[aprssig] The final WIDE2-1,WIDE1-1 solution!

I just changed my D7 from RELAY,WIDE2-2 to:

WIDE1-1,WIDE2-1

after sending several beacons, I see my packet being digipeated 3 to 4 
times.
All digi's in the local area are either UI-DIGI or UI-View32 smart digi's, 
with full dupe suppression.

Now, we have always known if two digi's see the same packet at the exact 
same time (and not as a retransmission from another digi), that dupe 
checking doesn't do anything. That is why I think I'm seeing 4 digi's of my 
one packet with the path noted above.

Below is a typical result of my beacon after having changed the D7 unproto 
from RELAY,WIDE2-2 to WIDE1-1,WIDE2-1
