Motivation / Problem
Sometimes a ship can't reach a dock while there is free space around it.

That's because only the end of dock is allowed to be a docking tile (and in this particular situation it's blocked by another dock).
Description
Allow all tiles around the dock to be docking tiles.
A savegame conversion is needed to update existing docks,
and I decided to do it without a bump.Limitations
