LinkSprite library

I finally have most of my linksprite camera functions working, so I have migrated them into their own library inside of my code repository. Of course there are bound to be some bugs, if you find any, please do let me know, best would be with the issue tracker in the repo.

On the hardware side, I added a toggle switch that makes my life substantially easier when reprogramming the Arduino. Previously I would have to remove 2 jumpers on the XBee shield, so that the computer could talk to the microcontroller to reprogram its memory. Now, the switch (see photo below) allows me to easily select between the connected and disconnected states.

Next few times I work on the code, I will probably be fixing bugs with my library, and general issues in my issue tracker. Soon I do want to connect the DIP switches though. And I'm always looking for ideas on how to improve my transmission rates because that is the single easiest way to get my battery life to increase.
