i2psnark:

- Rework PeerID class so it depends only on peer desthash, since
    peer ID is not available with compact format. Implement deferred
    lookup of destination.
  - Implement compact tracker requests and response handling
    (may not be the final format)
  - Fix Peer hashCode()
  - Java 5
