@vbaranov Please review it

[vbaranov]

@dennis00010011b

• Investor#1 has received correct quantity of tokens after finalization
• Investor#2 has received correct quantity of tokens after finalization

After finalization in Dutch Auction balances of tokens shouldn't be changed, because there are no reserved tokens for this strategy

2. I don't see the check, that non-whitelisted investors can't buy during crowdsale

3. We should also add checks, that if crowdsale is whitelisted, the owner can change whitelist before the start and during crowdsale

The rest looks good
