* I2CP, HostsTxtNamingService, I2PTunnel:

Implement Base32 Hash hostnames, via the naming service.
      Names are of the form [52-characters].i2p, where
      the 52 characters are the Base32 representation of our
      256-byte hash. The client requests a lookup of the hash
      via a brief I2CP session using new I2CP request/reply
      messages. The router looks up the leaseset for the hash
      to convert the hash to a dest. Convert the I2PTunnel
      'preview' links to use Base32 hostnames as a
      demonstration.
