EEEAB's Mobs - Nameless Guardian Returns!

This addon mod for EEEAB's Mobs adds a new arena structure that generates underground with the Nameless Guardian within it. At the top of the structure lies a crack at which one can jump through to enter the arena and confront the boss.

Also revises its entry information in the Boss Checklist mod and renames the Realmwarden's "Guardian Core" item since the Nameless Guardian drops a weapon with the same name.

The structure ID is "eeeabsmobs:nameless_guardian_chamber" for /locate

P.S: I did not build the arena, it's pretty much just ripped straight from the Coreforge Ruins (the room containing the Realmwarden)
