Missing configuration file may break CLI

[FrankNagel]

Cohen3.base.log_level breaks here if you use the CLI interface in non daemon mode and without a configuration file (or without a proper logging section). You will get an builtins.AttributeError: 'Section' object has no attribute 'upper' exception.

The reason for this behavior is, that you unconditionally add a loggging section in cli.py but only in daemon mode do you add a level attribute a few lines later.
