1710 ship_trade_in_factor starts at 100%, so it can be profitable to sit
1711 and buy the same ship over and over again. This bug predates Oolite
1712 1.65.
1713 Partial fix: make effective trade-in value 75% * ship_trade_in_factor%
1714 of the "raw" trade-in value. This still allows profitability! A better
1715 solution would be to unify the price calculation for trade-in and
1716 for-sale ships.
