Testnet Release With Fixed Post-EIP27 Sync

This release is corresponding to 4.0.31 with #1728 (a fix for #1726) merged. The PR being merged allows for syncing with the longest known testnet blockchain where both v0 and v1 pay-to-reemission contract syntax trees appear now.

The testnet is full of forks anyway, for reliable bootstrapping, please use trusted peers via following config:

scorex {
 network {
    knownPeers = [
	"213.239.193.208:9020",
        "195.201.82.115:9020" 
    ]
    peerDiscovery = false
  }
}

and remove peers/ folder (along with history , state , wallet/registry sub-folders in data folder before restart, in case of resync.
