Ethash2GB: MusiCoin has reached Epoch 96
PhoenixMiner and other Ethash miners can no longer mine MusiCoin.

So we will have to introduce Ethash3GB algorithm.

The following MPM miner files already support Ethash3GB:

- PhoenixMiner 3.0c (coming soon)
- ClaymoreEthash
- EthMiner

In addition to Ethash3GB-ready miners we'll also need to update the pool file (currently only MiningPoolHubCoins supports Ethash2GB).

I'll prepare a PR for this.
