closes #1023 Now we put on stack stackitem.Array instead of Interop, so we don't need old transaction-related interops anymore. Removed the following interops: System.Transaction.GetHash Neo.Transaction.GetAttributes Neo.Transaction.GetHash Neo.Transaction.GetWitnesses Neo.Attribute.GetData Neo.Attribute.GetUsage Also removed the following duplicated NEO interop: Neo.Blockchain.GetTransaction
