Versioned Transactions binary representation

In the new version, the transactions are signed by proofs instead of using a signature. So basically **signature **is replaced with **proofs. **In order to make API more consistent and flexible, all transactions will have version field and use proofs.

Proof

Proofs are an alternative way to authorize the transaction that is more flexible than signatures and enables smart contracts such as multisig and atomic swap. Each proof is a Base58 encoded byte string and can be a signature, a secret, or anything else – the semantics of a proof is dictated by the smart contract that interprets it. There can be up to 8 proofs at most 64 bytes each.
