Hapi-ly Accept Languages

Parses Accept-Language header on requests for HapiJS and attaches them to request. Extracts language, region, script, and quality as per RFC-5646 best practices. Based on hapi-accept-language with better tests, options, and failovers; uses accept-language-parser. Special thanks to OpenTable for their work.
