* Ported the snark bittorrent client to I2P such that it is compatible
      with i2p-bt and azneti2p.  For usage information, grab an update and run
      "java -jar lib/i2psnark.jar".  It isn't currently multitorrent capable,
      but adding in support would be fairly easy (see PeerAcceptor.java:49)
    * Don't allow leaseSets expiring too far in the future (thanks postman)
