Bugfix ppo2 high/low check in OC mode: The fallback option which is used in CC mode was applied to the OC mode as well. As result the check could be deactivated depending on the fallback state, even if a OC dive is performed. now the check will always be performed if the dive mode is OC. Added vibration warning: The internal buzzer of the GPIO_V2 may now be used as additional warning notificator. It can be activated using the check button in the customer view menu. The vibration will be active while the warning message is displayed in the dive window. In case the diver is in the menu then the warning will be active for a shorter duration.
