raw logging defaults to true...necessary?
sopel [by default](https://github.com/sopel-irc/sopel/blob/master/sopel/config/core_section.py#L134) does raw logging.  
You would need to manually add log_raw = False to config file to disable it.
Just wondering if having it on by default is really that necessary?
