Improved ocean fishing

[Cucuber]

I think that there should be some spots in the ocean that continually produce fish in the same place. This would ofcourse make fishing more viable as a food source but it will also make ocean exploring more fun because there is something more to find. More importantly, it would incentivise people to create fast boats. If you make a fast boat you would get more fish faster. This will also make people more likely to fight malbatross for the Winged Sail for fast sailing. I believe that the fish spawned should not despawn until it has hit some limit so that people can wait some time then go on their fishing trip. Going on a fishing trip will also give you a chance to find a message in a bottle without needing to sail aimlessly. You should be able to place ocean trawlers nearby the fishing spot for some automated fishing, though they have a limit on how much they can hold. I know that there are fishing spots already in the game (deep bass shoals) but some of them are random and they can spawn malbatross and maybe you don't want to do that.
