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

I cannot see that method in the diff, so it is probably something older, but fine...

AI will need to use CheckStepFerry or whatever to get list of all fields from which regular road can lead, I will investigate it...

Please look at this code: https://bazaar.launchpad.net/~widelands-dev/widelands/trunk/view/head:/src/ai/defaultai.cc#L3849

It would be convenient if equivalent of this was possible for waterroads, what do you think?

I still would like to have MOVECAPS_FERRY capability, so that AI would take random flag, and if it has this capability it would run map.find_reachable_fields() from this point to collect possible destinations for waterroads...

These are just few thougts for discussion...
