    Thanks to PL1 for defining the technical requirements.
  Created 3 mapping presets 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.
  Improved GUI for Windows 8 compatibility
