Adding servo management for pan/tilt
Adding servo management for pan/tilt

Servo range is 0-160 degrees. There is a hardware limitation for the moment, but when I find a shorter camera mounting screw, we can make the max 180 degrees. Note that passing the angle value of 999 resets the pan and tilt servos to their home positions.
