Reset Safety Stop display in case of a new descend: In previous version safety stop was displayed in while the stop depth was reached. The count down was interrupted in case of a new descend but the safety stop was still displayed, blocking the NDL visualization in the big font view. To avoid this scenario a restart function has been added which will return to NDL view in case of a descend > 2m. If just a short drop happend then the countdown will be continued when the safety stop depth is reached again. If that takes more then a minute the safety stop counter is restarted.
