Improve logging

Browse Source 
Everything that gets logged now has a log level associated with it.

The log level can be set with the new `-l` or `--log-level` arguments.

The defaul log level is `debug` for now. There aren't many things that get
logged but if the logs get spammed in the future it can be set down to `info`.
