PWT [Point Wish] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract ownership is not renounced (belongs to a wallet)

StandardToken.allowance(address,address).owner (#553) shadows:
- Ownable.owner() (#146-148) (function)
StandardToken._approve(address,address,uint256).owner (#754) shadows:
- Ownable.owner() (#146-148) (function)
Rename the local variables that shadow another component.

StandardToken.constructor(string,string,uint8,uint256,address,uint256).serviceFeeReceiver_ (#467) lacks a zero-check on :
- address(serviceFeeReceiver_).transfer(serviceFee_) (#477)
Check that the address is not zero.

Variable StandardToken._totalSupply (#460) is too similar to StandardToken.constructor(string,string,uint8,uint256,address,uint256).totalSupply_ (#466)
Prevent variables from having similar names.
