Automatic detection at sea

Any time a ship is in a sea area, not in the presence of enemy ships, and has not moved during the turn, at the end of the turn it has a chance to detect any other group of ships in the same sea area as itself. The details are, like, forthcoming. Bug the coder if you need the details and he hasn't added anything to this yet.
