[aprssig] Core Server Port changes

The APRS-IS Core Servers have today added several new port connections, 
allowing enhanced  flexibility in the filtering of the APRS-IS data 
stream.  Most notably, ports have been introduced which mirror the 
previously available ports, but pre-filter the stream to eliminate the 
non-amateur CWOP data.  Some amateurs have expressed concern about the 
cluttering of APRS maps by the vast number of CWOP stations.  Use of 
these new ports will eliminate this issue.

A new filtered history port has also been added which allows the same 
filter parameters previously available on the User Defined Filter Port 
(port 14580) to a 30 minute history port.  This can be useful for 
applications such as javAPRS that want a historical dump of data, but 
only in a particular area (or for particular data types, etc.).  This 
new history port, as with all history ports, is a one-way port that only 
provides data to the client.

New port numbers have been generated to provide the new functionality. 
Prior port functionality is unchanged.  The complete listing of port 
definitions can be found on the status pages of the core servers 
(first.aprs.net:14501, second.aprs.net:14501, and third.aprs.net:14501). 
  Information is also available on the Core Server Website 
(http://core.aprs.net).

Users connecting to the core servers are encouraged to review the new 
port options and modify their connections as they see appropriate.
