 a) Better crypto (replaced SHA1/DH/RSA1024 with SHA3/ed25519/curve25519)

 Don't allow New Tor nodes to build circuits with obsolete Tor Nodes unless
 they support the newer encryption version 0.3.2.9 - 2018-01-09

 Only use the old crypto to resolve old .Onion honeypots...........

 Only use SHA3/ed25519/curve25519 to build New 3 hop Circuits.  This will
 provide better anon for hidden services which use the same transport
 system.
