[2021] Fishing For Items (New Mechanic)

I added a new mechanic (for update 0.10.0.0) to fishing which allows players to catch items that are on the ocean or lake floor. This can be useful when your items fall into the water and you want them back. Plus it adds some surprise to fishing as you can now find mysterious items in the water. I plan on adding a lot more water based items (treasure chests, seaweed, clam shells, relics, etc), so this will be a great way to get those.
