Centered, and pin the Emergency button to the bottom.  Also made the emergency button bigger.

Made the buttons change color when they are clicked
added function to reset the watchdog timer
added uipicker to choose between animations
Re-arranged the animation button,
added a couple of other animations
added functions to support manual control of the AR.Drone over wifi (udp) and serial (AT) links.
Resetting to previous check in.  Contains Basic GUI to control the AR.Drone with AT commands.
