EnchantableBlocks

General:

• Fix default config not saving
• Rework registry/block system
  • This should have been part of the 3.0.0 update, but 1.17 forced me to release sooner than I would have liked. For developers, I apologize for the breaking changes. Really should have bumped version to 4.0.0 but it feels silly to increment major version so frequently.
• Added tests
  • Over the course of the last 10 months I've slowly been improving the plugin's code health. Both my general Bukkit library and this plugin now have over 90% coverage, with EnchantableBlocks having nearly 100% method coverage. This allows me to fix issues before I ship builds rather than after people encounter them.
• Added block-specific enchanting permissions
  • Existing permissions still supported, more fine-grained per-block settings included.
  • See the permissions wiki entry for details.
• Removed some dependence on Minecraft internals
  • Due to slight variations from Minecraft's process for enchanting, there's no point in using the internal Minecraft seed. All it does is add complications to the update process.

EnchantableFurnace:

• Add safeguards against Silk Touch failures
  • In the event that Silk Touch does fail again, it will forcibly refund the stored fuel cost when a furnace attempts to consume fuel.
• Unbreaking and efficiency now use an S curve for calculations
  • Provides smoother results for more extreme values
    • Makes negative levels of enchantments a little more interesting due to less extreme changes
    • Makes missing out on higher unbreaking less punishing so that enchanting in general feels more rewarding despite not receiving max level
  • Efficiency 1-10 largely unchanged (single tick differences due to rounding changes)
  • Unbreaking modified:
    • Base burn time for coal is 80s.
    • Unbreaking 1 burn time for coal 96s -> 100s
    • Unbreaking 2 burn time for coal unchanged at 112s
    • Unbreaking 3 burn time for coal 128s -> 120s
