Title: Added more TLDs to a blacklist to prevent connection attempts

In my logfiles I could see crazy attempts like this:
2014.05.04 01:51:57 org.jivesoftware.openfire.session.LocalOutgoingServerSession - Error trying to connect to remote server: eu(DNS lookup: eu:5269)
java.net.UnknownHostException: eu

This patch put all blacklisted tlds to a list and extend the list by some europe country top level domains.
