(svn r6640) -Fix: [autoreplace] autoreplace can now use the money for selling the old vehicle to build the new one
Say we got 40k for selling the old one and the new one costs 60k, then the player only needs 20k to replace

The new engine is still built before selling the old one for various reasons, but now the player gets a loan
of the sell value, which is always repaid when replace fails or the old engine is sold. The player will never notice this loan.
