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

Implemented or replied to your diff comments in revision 8852.
I can´t reproduce the ASan complaint you reported anymore, but I fixed several others that surfaced now, except for one on game-end that will follow soon.

Regarding the ferry target quantity: IMHO the ferry yards work like shipyards, which also produce until the player stops them manually. A target quantity would be especially difficult if the ferry yard is close two several oceans.

Some of the waterway code which you annotated is copied 1:1 from road code. Should I therefore leave it as it is, or change both the new waterway code and the original road code?

And saveloading – I don´t think it is really possible to preserve compatibility here, see my comment in MapFlagPacket…
