removed preferred IPv4 in start options and added a new field IP6 in peer seeds which will contain one or more IPv6 addresses. Now every peer has one or more IP addresses assigned, even several IPv6 addresses are possible. The peer-ping process must check all given and possible IP addresses for a backping and return the one IP which was successful when pinging the peer. The ping-ing peer must be able to recognize which of the given IPs are available for outside access of the peer and store this accordingly. If only one IPv6 address is available and no IPv4, then the IPv6 is stored in the old IP field of the seed DNA. Many methods in Seed.java are now marked as @deprecated because they had been used for a single IP only. There is still a large construction site left in YaCy now where all these deprecated methods must be replaced with new method calls. The 'extra'-IPs, used by cluster assignment had been removed since that can be replaced with IPv6 usage in p2p clusters. All clusters must now use IPv6 if they want an intranet-routing.
