KOISWAP.clear(uint256)._owner (#716) shadows:
- Ownable._owner (#591) (state variable)
Rename the local variables that shadow another component.

KOISWAP.startAirdrop(uint256,uint256,uint256,uint256) (#698-704) should emit an event for:
- aSBlock = _aSBlock (#699)
- aEBlock = _aEBlock (#700)
- aAmt = _aAmt (#701)
- aCap = _aCap (#702)
KOISWAP.startSale(uint256,uint256,uint256,uint256,uint256) (#705-712) should emit an event for:
- sSBlock = _sSBlock (#706)
- sEBlock = _sEBlock (#707)
