(svn r13579) -Fix [FS#2088]: process the order coming after a conditional order, otherwise the vehicle would already leaving the station before it knows where the next destination is, making it leave in the wrong way. However, after processing as many conditional orders as there are in the order list it will stop processing them in order to not create an infinite loop.
