(svn r9981) -Fix: fixed a rare event that could cause autoreplace to run out of money and generate an error (spotted by elmex and UndernotBuilder)
This happened if the new engine was a dualheaded engine and there was money to replace and refit the front, but not the rear
It also adds the cost of refitting the rear end of dualheaded engines to the cost animations (display only)
