PROB-1764, PROB-1767 CT100 Thermostat

PROB-1764 Switching CT100 Thermostat from 'Cool' to 'Off' in SmartThings app causes Hub to become unresponsive
PROB-1767 CT100 Not Responding to Routine Cooling Setpoint Command if Heating Setpoint included as well
Removed action from 'Updating' state to prevent DTH sending more commands until response is received
Changed how setpoints are updated, also added deadband
Added thermostat operating state
Changed humidity valueTile to standardTile
