(svn r10077) -Fix: FS#845 Cloning Trains Longer Than 8 Units Causes Crash
The problem was that if adding units to the clone (wagon by wagon) failed, then cloning wouldn't notice it and it made two half trains
Now it detects this case and it will make cloning fail. The string with the explanation for the failed move will be used in the error message so the user will know why it failed.
