whois_server_id: Moved swhoisd up because it seems more distinct than some of the other ones, which should just be auto-detected.
id.go: Removed a lot of junk for detecting specific protocols used by one server.  Starting to create a generic protocol detector.
id.go: Check if number of matches is 0 and complain because we did not recognize it
id.go: Better logging, using an instance of log.Logger for each server.
