Code review comment for lp:~widelands-dev/widelands/ferry

I did not think of the several oceans problem.

I think it would be good if you could fix both the new and the original road code. This branch is huge anyway, so I don't mind having more changes in it.

I can look into the saveloading if you want. Just leave the annotations in until everything else has been finalized and I'll have a look if I can make it work.
