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.

1. Compile the pack utilities

cd src
make checksum_final_add_fletcher
make OSTC4pack_V4

2. Edit create_full_update_bin.sh

Set BUILD_PATH to the location where you build the individual parts
of the firmware using the OpenSTM23 IDE. 

Set BUILD_TYPE the either Debug or Release (or any other build style you 
defined in the OpenSTM23 IDE).

Set the "build project names" as defined in the OpenSTM23 IDE.

3. Simpy run create_full_update_bin.sh

Run it in the ostc4pack folder of the repository, and a file with name
like OSTC4_<date>.bin is created containg the individual blobs.
