Add new log level (closes distributhor#21)

Adds a new log level between `--verbose` and `--silent`.

Defaults to the new log level. Added new option `verbose` that
re-enables verbose output (previous default) if set to `true`.

This allows easier debugging without entirely compromising on privacy
and security (domain, IP addresses etc.). For more details see distributhor#21.

This also reduces the propability of replay attacks as mentioned in distributhor#22,
as the signatures are no longer logged by default.
