174 - Unnecessary `require` Statement

The following require statement in Blacklistable.sol can be removed: require(to != address(0));

Indeed, this check is implemented in the _transfer() function in the ERC20.sol smart contract.

Recommendation:

Consider removing the require statement for gas saving purposes.
