Raises the item stack limit from 64 to a value you configure, and keeps containers, slots, saved data, network sync and bulk crafting consistent with it.

What's new

v21.1-1.0.4-hotfix

- Fixed a dedicated-server crash: shift-crafting in the Sophisticated crafting tab called the client-only unlock key class, which NeoForge refuses to load on a server. The server now reads the unlock state itself.
- The same code path was corrected on 1.20.1, 1.21.1 and 26.1.2, so servers on any of these versions are safe.
- No gameplay changes; single-player behaviour is identical to 1.0.4.
