Add send_transaction2 support (#8)

* add SendTransaction2Args, send_transaction2 rpc method, calls send_transaction2 unit test

* add text-encoding dev dependency to run unit tests

* update api.transact

* minor

* update GetInfoResult

* add transactWithRetry unit test

* add useOldRPC and useOldSendRPC options

* minor

* rm retryTrx, make like cleos, use retry block num and retry irreversible, add assertion, pass retry blocks if not irreversible, make num blocks optional param

* update json rpc unit tests with blocking 10 blocks and blocking irreversible

* update node test, add irreversible check, update to 10 blocks

* update README.md, add '?' for optional params

* use 30 blocks versus 180 for irreversible

* use send_transaction2 rpc by default without retry trx feature

* enable failure trace default, make default send_transaction2 rpc

 `transact()` is used to sign and push transactions onto the blockchain with an optional configuration object parameter.  This parameter can override the default value of `broadcast: true`, and can be used to fill TAPOS fields given `blocksBehind` and `expireSeconds`.  Given no configuration options, transactions are expected to be unpacked with TAPOS fields (`expiration`, `ref_block_num`, `ref_block_prefix`) and will automatically be broadcast onto the chain.
 
+With the introduction of Mandel v3.1 the retry transaction feature also adds 5 new optional fields to the configuration object:
+
+- `useOldRPC`: use old RPC `push_transaction`, rather than new RPC send_transaction
+- `useOldSendRPC`: use old RPC `/v1/chain/send_transaction`, rather than new RPC `/v1/chain/send_transaction2`
+- `returnFailureTrace`: return partial traces on failed transactions
+- `retryTrxNumBlocks`: request node to retry transaction until in a block of given height, blocking call
+- `retryIrreversible`: request node to retry transaction until it is irreversible or expires, blocking call
