Added auto detection functionality for sensors connected to the external interface: O2 sensors may be connected to the analog input as well as to the UART. The GUI visualization provides three slots for ppo2 display. Beside detection of sensor kind the task of the function is to place the available sensor in this three slots. CO2 has its own communication slot outside the ppo2 channel. The result of the automatic detection is communicated via the sensor map.
