Changed default values: Invalid pressure was signalled using the float 100.0 causing the OSTC to enter dive mode if for some I2C communication was disturbed during startup. The default value for button responsitivness was set to 85% without considering the needed HWOS transformation calculation. Applying that the value for 85% is 51 PowerOnReset is state is now identified using the same functionality as already introduced for the battery charge handling. Initialization of pressure sensor in case of I2C problems only if the initialization was not successfull before: The pressure sensor is reset via a I2C commend in case of a I2C error. A reset might be helpfull in case of a "hanging" ADC operation but that would not be indicated by a I2C problem => resetting the sensor in case of a I2C problem might cause (small) change of pressure value

------------

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.
