Changeset 18114

Message:

Added SLEEP task which is a shutdown without locking the drive and disconnecting the bias crate; restructured RATESCAN2 to switch voltage off before closing the lid or switching the voltage to the breakdown voltage in case of voltage on to avoid moving through full moon with full bias voltage as in data taking. Ramping voltage back to nominal after movement.
