Title: Print a warning message if we encounter a config file directive we don't understand

Recently found myself helping someone with an issue where they had a old config file (pre 66f7271c, where `logfile` became `accesslog`) and wondered why their logging had stopped. This patch adds warnings for 'unrecognised directives' (anything in `cfg.items()` not beginning with `_`).
