Invariable Paintings

Additions:

• Some painting variants may now only be obtained from specific sources. E.g: the Wither painting is now exclusive to the nether, and the elemental paintings can only be bought from Wandering Traders. The system behind this was built so that modded (untagged) paintings will remain available from most sources by default.
  • The loot function invarpaint:lock_variant_randomly can optionally specify a pool of variants it will be restricted to.
  • Merchant trades can be given exclusive deals by placing paintings into the tags #invarpaint:exclusive/villager or #invarpaint:exclusive/wanderer.
• The inventory-desync fix is now fully server-side.
• The server now provides a fallback translation for the warning when placing a painting into a smaller space.

Removals:

• Vanilla CITs are no longer an optional resource pack. (They are back into the core assets.)
• Removed the deprecated name minecraft:lock_variant_randomly.
• Removed experimental crafting recipes. (Re-published separately.)
