Allows squids, dolphins and other water mobs to swim through air using the new "waterlogged" block attribute, by dynamically making air blocks around them waterlogged, i.e. behave like water.
- Flying dolphins wot!
- Flying guardians shooting lazers through the sky holy shit!
- Flying mobs make surrounding air waterlogged, which means it will behave like water for all entities (items, players can suffocate, etc.)
