feature, debug: make simulator write a logbook entry When compiling the code with -DSIM_WRITES_LOGBOOK, the simulator writes to the logbook. This is for debug purpose only. This commit does *not* define this SIM_WRITES_LOGBOOK, so when compiled, things are functionally unchanged. Caveat 1: a simulator generated log cannot be advanced with +5 min. It needs to run in real time. Caveat 2: The generated log is currently not "complete". For example, CCR setpoint switches are not logged. There are likely more small events not logged. This means that a sim generated log is not a full replacement for real dive testing. Signed-off-by: Jan Mulder <jlmulder@xs4all.nl>

README.linux
------------

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.
