Added log entry for surface GF: The surface GF has been added to the logbook data. A function records the GF which is present while entering close to surface condition for later storage. This is needed to avoid that an already decreased GF (after dive mode exit time) GF is stored. The surface GF is shown at logbook page1 and is available in the header data for external logbook services.
