Flints 'n' Nuggets

A simple mod that changes up the progression of Minecraft.

Firstly, it adds a set of flint tools, which are: the Flint Hatchet, the Flint Mattock and the Flint Knife.

Secondly, it changes the smelting system to make it harder; now a Raw Iron after smelting will turn into an Iron Nugget, the smelting process is twice as fast.

WIP:

1. Add small rocks/flints laying on the ground;
2. Add Cordage which will be used in the crafting recipes of those tools;
3. Make breaking trees with hands impossible;
4. Change the smelting system of Minecraft netirely, introduce Pit Kilns;

My aim with this mod is to replicate the TerraFirmaCraft early progression experience (maybe even other things like metalworking if I get to it)
