New miner for Connor (ETHO)

[DPolygalov]

Feedback from users. Need: Implement mining for Ethereum Forks/Clones - theys should work basically identical. Right now ETC and Ether-1 (ETHO) https://coincodex.com/crypto/ether-1/ are more profitable to mine than ETH. If you implement these ETH identical chains, SONM can already be more profitable than mining ETH
