Don't load etc/schleuder.yml?
It's a problem for debian-packaging: where to put etc/schleuder.yml.
We're currently loading it as defaults, which are overwritten by the contents of /etc/schleuder/schleuder.yml.
We could either:
- require that /etc/schleuder/schleuder.yml contains all settings (not only the ones you whish to overwrite)
- encode the defaults as a constant into Schleuder::Conf (like we did in schleuder-cli)
