Title: Hack support for external referers.yml 

Hello guys, great Work!

I just hack my way into your project to add support for an external referers.yml file in the ruby gem.

Im going to build a referer filter for logstash similar to the useragent one (which is based on ua-parser) and need this feature.

Hope the PR is welcome!
