Transmitter update: 0.2.3 - Price feed update

---

With the recent commit f33aebe2, transmitter started supporting HIVE blockchain.

Regarding price feed updates, I have only Bittrex adapter enabled at the moment. As other exchanges support HIVE, I'll be also updating the adapters in newer versions.

Quickstart (w/ Docker)

---

• Clone the repository

$ git clone https://github.com/emre/transmitter.git
$ cd transmitter

---

• Fill the configuration

$ vim config.json.docker

---

Minimum config.json.docker example:

{
    "WITNESS_ACCOUNT": "emrebeyler",
    "SIGNING_KEY": "<private_signing_key>",
    "NODES": ["https://api.hivekings.com", "https://api.hive.blog"],
    "MARKETS": ["bittrex"]
}

• Build the image

$ docker build -t transmitter .
