CCR option: display o2 sensor data

This patch creates the possibility of viewing the individual sensor
values when the po2 button on the profile toolbar is activated. This
follows exactly the procedure for optionally displaying the setpoint
values while viewing po2. A checkbox in the preferences panel determines
whether sensor information is shown. By default it is set to OFF. When
checked, and the po2 button is activated, sensor1 values are shown in
grey, sensor2 in blue and sensor3 in brown.
