feat(santoTirso): logic from santo-tirso branch merged

Changes:
* merged logic from `santo-tirso`,
* created skeleton of an internal semi-plugin hosting `addressReceived ` method (currently called `temporaryName `),
* `newAddress` method moved to `wallet` plugins ([here](https://github.com/lamassu/lamassu-bitcoind/pull/5) and [here](https://github.com/lamassu/lamassu-blockchain/pull/8)),
* in `routes.js` `send` method moved to maintain routes declaration order.
