Second challenge dungeon for patrons (Patreon)

• NEW DUNGEON: Miners have unearthed a dungeon of ancient war machines. They need you to clear it out before the machines can escape.
• Fixed an issue where party HP bars would stop updating
• Made got GUI less likely to stack heap
• New HUD tracking functionality for level developers.
• Fixed an issue where LTB visuals would get stuck

I intend on adding one more challenge dungeon before releasing it for public. Likely a demonic/imp dungeon.
