Update gitignore file, removed the old info about the old wiring batch from the README.txt. Update the version number to 1.3 in the build.xml file and added Chris's PixelStepper code which uses all the developer shield features.

-somewhat different, with the following mappings:

 If you are using a small number of LEDs the Arduino itself can provide power
 to the strand, but for a significant number of lights (greater than 5) an
 external power source should be attached. The Arduino will control the lights
