Adds several more uses for plastics (Trinkets, Trash, Decor, and Killing the Environment) (#48337)

* Initial Commit, Plastic Boxes and Soda Rings. Basic carp interaction.

* Beads, trash created from breaking plastic, carp eat plastic properly.

* Cleans up sprites, adds designs to autolathe, and adds plastic plants

* Icon Conflict more like Ion Comblict because I can't spell

* Oh neat, there's already a party crate. Added Beer/Soda 6packs to the crate, adjusted price accordingly.

* Aaaaaaaaaa runtime loop.

* You win this round travis.

* Makes the in-hand sprite the soda can sprite because honestly it's close enough don't @ me

* Typo.

* Merge conflict, style changes, FINE CARP DON'T BREATHE.

* BEGONE CONFLICT BEGONE FROM ME
