v1.0.2.1 08/04/2013
  Add mechanical rotary joystick firmware to support devices like this one: http://na.suzohapp.com/joysticks/rotary_optical_joy.htm . Thanks go to PL1 for defining the techical requirements.
  Created 3 preset firmwares for the mechanical rotary joystick (P1 Rotary, P2 Rotary and 2 Player Rotary)
  Remove LED output options from default custom mappings as a precaution against short circuit for those unfamiliar with wiring requirements.  Existing users will be unaffected unless selecting to revert back to default map in the customiser.
