Add MRV token for Macroverse

If you do consider token pull requests, here is one for you. The Macroverse token, MRV, functions as a tokenized software license to use Macroverse, a procedurally-generated universe on the Ethereum blockchain.


The token is here: https://etherscan.io/token/0xAB6CF87a50F17d7F5E1FEaf81B6fE9FfBe8EBF84

The source is here: https://github.com/NovakDistributed/macroverse/blob/master/contracts/MRVToken.sol

Verification of the contract source on Etherscan is blocked pending updates in Etherscan to support the "runs" optimizer parameter used by Truffle; more information on that is here: trufflesuite/truffle#456 (comment)
