- removed default / fallback variant; you are forced to define the variant of your choice now or build will stop with an error 

- added condition in config.h to either take setting from platform.ini or config.h
- homogenized default_envs naming; all variants now have VARIANT_ as prefix
- added nunchuck variant in platform.ini and config.h
- added PPM variant in platform.ini and config.h
- README: added jan's nunchuck breakout board repo

Nunchuck or PPM working bad: The i2c bus and PPM signal are very sensitive to emv distortions of the motor controller. They get stronger the faster you are. Keep cables short, use shielded cable, use ferrits, stabilize voltage in nunchuck or reviever, add i2c pullups. To many errors leads to very high accelerations which triggers the protection board within the battery to shut everything down.
Recommendation: Nunchuck Breakout Board https://github.com/Jan--Henrik/hoverboard-breakout
Most robust way for input is to use the ADC and potis. It works well even on 1m unshielded cable. Solder ~100k Ohm resistors between ADC-inputs and gnd directly on the mainboard. Use potis as pullups to 3.3V.
