Quick update to the sketches...

I just did a "silent" upgrade to the ArdCore sketches. I added some basic license text, which points to our release of these sketches using the Creative Commons non-commercial attribution license. I really like the option of using CC's license as a way to share with the community without losing all control of the result. I hope that you all find the sketches to be useful, and expect to continue updating them as progress continues.

On to the boards!
