-3 is for sea <-> sea and sea <-> city movements

there is no current behaviour as such because there is no division into
sea and land_move_cost.  But right now move_cost for between ocean tiles
is -3 and sea <-> land is a local equivalent of MAXCOST unless there is a
city on this land.  However in such mixed cases there are explicit checks
and move_cost is not used directly.

It's all pretty involved and complicated, having ready-to-eat move_costs
would be so much easier and faster...
