Re-activate logging capabilities #23
Description
There are different transports in our CLI. By default everything is logged to your system out (your terminal, most likely), but additionally you can activate a file transport that writes the output of the command to a file in the current working directory. This can be useful to provide details in case of problems / an error (for example).
It was deactivated when upgrading the CLI, but the code is all still there... just needs to be tested again.
