Mana and Artifice

What should be pretty much working, in no particular order. By working I mean I did a cursory test, and haven't done a deep dive into it:
- Custom Villagers and Structures
- Villager Trades
- Advancements
- Spells
- Rituals
- Constructs
- Manaweaving
- Worldgen Structures, and the boss arenas should spawn more accurately. There still may be a couple things that spawn inside the boss structures, blocking movement or access (looking at you, basalt pillars -_-). Remember creative mode can bypass the protection so you can clear a path if needed. So far though they're actually *there* every single time. We take the win.
- Vinteum Ore Gen
- Chimerite Drops
- Beheading Drops
- Particles
- Mob Spawning. Lantern wraiths still need tweaking. I know.
- Bosses
- Mob AI
- Servers

Known Issues:
- Trying to join a game can sometimes time you out with "NullPointerException" and kick you to the server list (even in singleplayer). Just try again, it should work on the second time.

It's mostly a straight port except for:

Intentionally Removed Things:
- Entity configs, as these are datapackable now
- Faction sharing of wellspring power. I want to do better and it was being annoying to port. So, yeet.

Intentional Changes:
- Fortune now affects chimerite drops, and is configurable via datapack. It will pick from the tool you mined the block with, or your ring fortune level - whichever is higher. This affects both amount and chance.
- Bouncy has been toned down, should lose vertical velocity much faster. This will inevitably change the fling travel meta, but when you weren't traveling it was more annoying than helpful. Consider flinging downward to travel and keep more velocity.
- Added an event for when broker trades are generated as per requests. Added one for the Wandering Wizard too while I was at it.
