Prim's Stranger Things

-Added new kinds of True Sight visions as build up to the "main event".

-Added a 40 second build up to a horde ambush to alert the player of it

-Fixed tracking for pet Demodogs molting into Demogorgons.

-Added the Dead Underdark and Dead Underdark Cavern.

-Removed the caches of original blocks and biomes for tunnels to hopefully lessen the TPS strain.

-Changed tunnels to act as "tubes" without holes, making them harder to enter.

-Changed Muddled Blocks to be harder to destroy.

-Added the ability to check details on a tunnel system with /tunnel status.

-Added PSYCHIC damage type, allowing for all damage dealt by a player with their powers to be tracked to them.

-Added a modifier for threat gain when psychic powers are used for the damage.

-Changed the default buffer range on Burrow Points to 200.

-Added multi-type threat capping. Allowing for some more consistent gain of threat level before the cap.

-Fixed issues with Catogorgons not burrowing and Slugs, Pollywogs and Frogogorgons getting "bored" of you and leaving.

-Added victim level gain when killed by the Flayed or Demos.

-Removed snow layers from the Upside Down. (Will require a fresh sync)
