change the syntax for value announcements to <value>[:<port>]
fix value appending and improve interface
change warning to info message
minor grammar fix
Implemented the new authentication feature; create a public/secret key pair (kadnode --auth-gen-keys) and 'announce' the secret key (only the sha1 hash of the public key will be send out actually). A lookup of the public key on other nodes will find the node and verfiy that the found instance really has the secret key belonging to public key.
add some documentation about the node authentication feature
remove --auth-port; use the DHT socket for the authentication feature instead
