New Arduino library for DFRobot XBee Gamepad controller

In case anyone's interested, I'm working on a new library for the DFRobot Gamepad Controller with XBee module running in 802.15.4 API-2 mode. It incorporates Andre Wrapp's existing and very excellent xbee-arduino library, but will hopefully facilitate gamepad data handling at both transmitter and receiver ends.
