The foreclosureTime and foreclosureTimePatron functions don't work when the token is new (ie no patron yet)

[JasoonS]

It tried to divide by zero when a token is new when calling this function:

    function foreclosureTimePatron(address tokenPatron) public view returns (uint256) {
        // patronage per second
        uint256 pps = totalPatronOwnedTokenCost[tokenPatron].div(patronageDenominator).div(365 days);
        return now.add(depositAbleToWithdraw(tokenPatron).div(pps)); // zero division if price is zero.
    }

since totalPatronOwnedTokenCost[tokenPatron] can be zero, and you get a divide by zero issue
