Bugfix display of deactivated sensors:
In the previous version disabled sensors had been show after startup. Rootcause was that the deactivation state was taken from the divesettings instead of the common setting. After startup divesettings are not initialized and therefore all three sensors were displayed even if one or more were disabled. This has been fixed by using the common settings in case that the OSTC is not in divemode.
