- Make curve://HOST/PUBKEY URLs work (equivalent to specifying two arguments, tcp://HOST PUBKEY, on the command line). - When we get a response that looks bt-encoded (starts with d/l/i and ends with e) then write it as binary rather than having Python display the bytes representation. This allows piping it to lokinet's `contrib/bencode-dump.py` to dump the contents.
