Ownable.initialize(address)._sender (#471) lacks a zero-check on :
- owner = _sender (#472)
Check that the address is not zero.

S4FE.transfer(address,uint256) (#613-618) compares to a boolean constant:
-require(bool)(msg.sender == owner || transferLocked == false || transferWhitelist[msg.sender] == true) (#614)
Remove the equality to the boolean constant.
