XWALL.tokenSale(address) (#161-184) performs a multiplication on the result of a division:
-_price = _eth / salePrice (#167)
-_tkns = saleChunk * _price (#168)
Consider ordering multiplication before division.

XWALL.viewSale().privateSaletokensSold (#190) shadows:
- XWALL.privateSaletokensSold (#141) (state variable)

XWALL.startSale(uint256,uint256,uint256,uint256) (#200-206) should emit an event for:
- saleChunk = _saleChunk (#201)
- salePrice = _salePrice (#202)
- saleCap = _saleCap (#203)
Emit an event for critical parameter changes.
