Infested: Swarms and Spiders

(Resubmit, I noticed an error that caused the Bug Stew to remain in a player's inventory after feeding it to a B. Beetle)

Added a new mob -- The Brilliant Beetle, from Minecraft Legends! The Brilliant Beetle can be found in Jungle biomes, and is tamed using Cocoa Beans.

After taming the Brilliant Beetle, you'll be able to ride it. Like in Minecraft Legends, the Brilliant Beetle is capable of scaling walls. It also falls more slowly, allowing you to control it mid glide. Most of the time. I had to import some custom code and it's slightly buggy. This will hopefully be fixed when the Java Recode is complete.

Added the ability for Tamed Spiders to climb walls like regular spiders.

Updated the texture and name for the entity previously referred to simply as the Beetle, now called the Crimson Beetle.
