Bugfix initialisation of surface pressure:
A reset of the RTE less than one minute before a dive starts may cause problems in the depth calculation because the default pressure is not set yet. To avoid this the first measured pressure value will now be used as stable surface pressure to close the gap till the stable surface pressure is evaluated.
