[aprssig] List of APRS web services

[scott at opentrac.org]

I don't think I've ever seen a comprehensive list of websites that provide
web-based APRS services, so I've started one on the Wiki:

http://info.aprs.net/wikka.php?wakka=WebServices

If there's a good list somewhere, let me know and I'll incorporate that.
Otherwise, either add it to the Wiki or mail it to me and I'll update the
list.
