Change Equihash Algo Params to 192_7

[ghost]

Set to 618000 but adjust accordingly. I pulled together the various branches across different repos and we have ;

• Algo change
• lwma-1
• testnet maturity config

And I added versioning etc

See testing log here; https://gist.github.com/grandmasterglitch/9fd638705677ab646f65ef1772350abc

ACK this hardfork; should improve network stability.
