Get registered domain from the Public Suffix List.

From country to country domain tld changes. There is no algorithm which can detect domain names. PublicSuffixBundle grabs the registered domain name from an valid URL depending on the registered domains list at publicsuffix.org.

An excerpt from publicsuffix.org:

A "public suffix" is one under which Internet users can directly register 
names. Some examples of public suffixes are .com, .co.uk and pvt.k12.wy.us. 
The Public Suffix List is a list of all known public suffixes.

The Public Suffix List is an initiative of Mozilla, but is maintained as 
a community resource. It is available for use in any software, but was 
originally created to meet the needs of browser manufacturers.

This Bundle depends on the php library of dkim-reputation.org. It is uploaded to Github by Leth
