Breaking changes for 1.20

[KnightMiner]

To anyone discovering this issue looking for news about 1.20, see the FAQ. This issue is simply a TODO list, not an indicator of update progress.

API changes that can support migrating old behavior

These changes can be added without breaking addons.

• Look into using GameTest for automated tests, not sure how long our method will keep working as mojang changes bootstrap (plus world sensitive tests would be nice to have)
• Books: Remove all uses of named section transformers in favor of generic section data transformers
• Replace tank block model property with a fluid and a capacity property
• Split castable tool casting from castable part swapping, allows us to do tool casting over a non-consumed cast and part swapping without a tool casting recipe.

Tools

• Support global tool definition data loaders
• Support merging on tool definition data? May be redundant to above
• Migrate away from tool loot hook to standard global loot modifiers
• Consider - make tool building recipe contain parts list. Move part swapping logic to tool building recipe.
• Allow composable modifiers to merge modules from multiple data packs.

Breaking changes for 1.20

Tools

• Move modifier slot colors to Mantles resource color manager
• Narrow return types on ToolStack methods to use NamespaceNBT instead of ModDataNBT when reasonable

Modifiers

• Migrate inventory modifier to modifier modules

Recipes

New 1.20 Features
