Boat locks#1552

Either existing locks temporarily keep boats from despawning, for about three days -OR- make current lock behaviour tied to a crafted item not requiring as many resources. I understand not wanting to let people hang onto boats on a semi-permanent basis, but the current boat locks are very overcosted for what they do.

I may be wrong, but it seems like the time before despawn has benn lengthened by the last pasth. Which is great.

But I think having boats persisting longer than a day would be unworkable, as it would result in the map being littered with unusable locked boats.
