    Add "-pow7 1" option to support Monero hardfork(hardfork activation height: 1546000).

    FYI, "ssl://" is specified for secure network connection.

    You can mine without this option but it is recommended to use because Claymore miner's devfee gets lower with this.
    Also, it would help some outer firewall disconnection issues time to time.
