Apologies
Firstly, I want to apologize for being silent for a very long time and not updating my plugins; the reason why is as follows:

I've been struggling emotionally, and busy with other things - and on top of that, my computer that I use for developing died, so I was discouraged from working on the plugins. I am on a temporary laptop right now.
Anyways, now onto the update;

This update mainly brings 1.18 support, but it is also a complete rewrite of the plugin itself. I decided to take out the Shrines and Custom Items + Mobs.
They may return in the future if you guys want, but I might have it as an addon to this to keep things neater. This is meant to be just improvements to Netherite, nothing too crazy.

And to be completely honest, the addition of the custom items and such kinda bogged me down a little, because it meant I had to update my other plugin at the same time as this one for this one to even function.

The config has also completely changed, I decided to migrate it to json, and simplify it a bit more.

The Smelting section has been compressed down into 1, same settings as before but the 'type' setting can be 1 of the 3 below:
FURNACE - This will make it to where you can smelt Ancient Debris into scrap in the Furnace only.
BLAST_FURNACE - This will make it to where you can smelt Ancient Debris into scrap in the Blast Furnace only.
BOTH - This will make it to where you can smelt Ancient Debris into scrap using both.

The main thing being there's no longer multiple different options relating to how Netherite items will be crafted, instead there's a single option where you can put 1 of the 3 below:
VANILLA - Netherite item creation will function as it does in the base game (Smithing Table)
IMPROVED_VANILLA - Same as above, except it brings the ability to upgrade other tool tiers using the Smithing Table (e.g Wood -> Stone) and the ability to customize how much of whatever resource is required to upgrade. (This also comes with a new settings; repair on upgrade, it does as the name implies - the upgraded item will be repaired.)
CRAFTING_TABLE - This entirely disables the Smithing Table, and instead makes Netherite crafted how you would the other tools (e.g 3 Netherite Ingots and 2 sticks for an axe or pickaxe)

Thank you for your patience, and I hope this update makes people happy with 1.18 support.
