Quick test for latest Arduino based Blinks API

Blinks Send and Receive Test

/*  Blinks Send/Receive (Test)

 *  IMPORTANT: To use this code in Arduino's IDE, first move the Move38-Blinks folder
 *  into the right directory i.e. <user home directory>/Documents/Arduino/hardware/Move38-Blinks
 *  Then open the Arduino IDE and select Tools > Board > "Move38-Blinks"
 *  Now you should be good to go :) (thanks to the hard work of Josh Levine – josh.com)

Still some flakiness but this should work..,

You need to pull this commit which fixes a bug that made all values returned from iRreadDibit() have bit 4 set....

Also, seems like I need to cycle the sendstate once though to get receive to work. Hmm...

I am also seeing occasional wrong color pop up in receive state. Hmmm...

Need to track both these down.
