* DataHelper: Fix broken byte[] compareTo() used by XORComparator,

      was not doing unsigned comparisons!
    * Floodfill rework part 2 of N:
      Store closest to the key, subject to last failed
      lookup and store stats.
    * FloodfillPeerSelector: Use standard XORComparator
      instead of messing with BigInteger
    * FloodfillVerifyStoreJob: Set correct timeout for
      requeued store job
    * KNDF: Rework getPeerTimout() to use 1 day averages,
      and lower the min, max, and multiplication factor.
    * Publish jobs: Lengthen timeout to 90s (was 30s for
      routerinfos and 60s for leasesets)
    * StoreJob: Limit max peer timeout to 15s for direct stores
