(svn r5465) -Feature: [autoreplace] replacing from a train engine without cargo capacity to one with cargo capacity will now make autoreplace refit the engine to carry the cargo type from the last wagon in the train
if the train is carrying the type of cargo, that is default for the engine, it will not be refitted
if the last wagon do not carry cargo, the refit will be to the type of the last wagon, that do carry cargo
