Deleted BoostUnit, since the new protocol has prescribed units for a particular mode. Implemented helper-function for turning javascript numbers into a bytearray. Changed generateInputCommand()-function delta-parameter to be int32 according to the new protocol. Fixed issue that whenColor hat-block didn't work until dropdown value changed.
