Patch notes for v0.8.1

Train designer, inspector, and train line windows now group wagons by default, making it much easier to design and manage long trains. * Train inspector now has a more compact layout with inline progress bars. * Added ship recovery - ships can now be recovered to the world edge or their destination (except ships currently moving cargo). * Docks can now be built on out-of-bounds ocean tiles near map edge. * Improved ship pathfinding with better support for out-of-bounds navigation. * Trade docks now require a minimum ocean depth of -2 instead of -3, making them easier to place early on. * Fixed train alignment issue with T2 locomotives when placed in the middle of a train with wagons on both sides. * Fixed that pumps and dumps could cause save loading issues. * Fixed various issues with terrain bounds checks for ships and ocean-related buildings.
