Datalink library 1.0.1

Datalink library for Linux uses the SVGAlib to send data to the Timex DataLink watches.
You will need SVGAlib installed and the development headers and libraries for SVGAlib to compile against.
Compiling:
Type make depend to make the dependences.
$ make depend
Then just type `make` on the command line.
$ make
Installing:
Type `make install` on the command line.
% make install
The default locations of the installed programs are:
/usr/local/lib/libdatalink.so.1
/usr/local/lib/libdatalink.a
/usr/local/include/datalink.h
/usr/local/bin/svgablink
/usr/local/bin/serblink
/usr/local/bin/setwatch
Enhancements:
- Fixed the setwatch options of -app and +app to say appointments instead of wristapp.
- setwatch was trying to run svgablink with -150S instead of -150s
- The -file (for creating a DEBUGOUTPUT) was broken, fixed.
