[aprssig] New version of WinAPRS

[Mark Sproul]

WinAPRS Version 2.7.7
MacAPRS Version 3.7.7

     * Major improvements in Tiger map drawing. Specifically the first 
time a map was drawn it took awhile to figure out all of the shaded 
areas. This has been speed up dramatically and at the same time uses 
considerable less memory. HOWEVER, it takes a little longer to 
process the map files into binary. It DOES NOT require the ascii 
files to create the new version of the binary files.

     * Back ground drawing. Much of the tiger map drawing is now done 
in the background. This speeds up many of the map operations.

     * Support for Toporama Canadian map images This covers 100% of Canada

     * Added support for Census Bureau Gazetteer place name file. This 
includes searching by city.

     * Added support for GPS data $GPNVP, this is a special, non 
standard NMEA sentance used in Korea and Japan. This was added at the 
request of Korean users.

     * Added TRUE rotated labels option for Tiger Map display
