Added function to evaluate the state of the surface pressure history memory Activation of the computer during or short after landing caused a switch into divemode which could then not be left. To solve this the history memory is evaluated for significant pressure changes as the would not be expected in "normal" condition. In case of such a event (unstable) the pressure limit to enter dive mode is set to an absolute value (instead of relativ in normal mode)
