Bugfix sensor de-/activation handling: In the previous version a CO2 sensor could cause a not used analog channel to be displayed. Rootcause was that all sensor type, not only o2 sensors, were used for o2 sensor deactivation evaluation. The deactivation state is the criteria if a value is displayed or not. In the new version only o2 sensor type are used for handling of sensor de-/activation state. In addition the cursor will now be set to the first valid sensor entry in case sensor slot 0 is empty.
