Describe your changes

• closes refactor TxResult event #20

The TxResponse type is updated to contain a typed inner_tx: TxResult for inner txs and some of its other fields are now typed. This is to make it possible to check a tx result in the client before taking further actions that depend on the result.

Stdout from a transaction now looks like this:

Transaction added to mempool.
