[aprssig] Compromise WinLink object proposal

"Encourage maybe but don't mandate..."

Gating by explicit call won't work.  Too much trouble when stations
are continuously coming and going.

It was simple to create a controlled CWxxxx-to-RF widget simply by
filtering locally on the Lat/Long.

Now, with the improved rules at the APRS-IS feeds, it's possible to
receive (and thus gate) only the objects of local interest. 

Anybody gating everything where it's not appreciated such as a busy 144.39
region will certainly be educated by their local users.

There are other places, and frequences, where it will be a good thing.  Don't
prevent the good just to try and elminate  potential problems that can be resolved
with education.
