Change TNT to Gunpowder

Since Minecraft has an overall subtle medieval theme, I thought it made sense to change the one and only explosive in the game to one that actually existed in Medieval times.

TNT was invented in 1863 by Julius Wilbrand.

Dynamite was invented in the 1860s by Alfred Nobel.

GUNPOWDER was invented in the 10th century C.E. right in the middle of the medieval period by the Chinese.

It was introduced into Europe in the 13th century, still within the medieval period.

It is the earliest known chemical explosive.

The ingredients for Gunpowder (or 'Black Powder' as it was known), are Sulfur, Charcoal & Saltpeter (Potassium Nitrate).

The first two already exist in Minecraft, and with the 1.14 'composter' block, perhaps a new material "fertiliser" could be introduced to be used as saltpeter to craft gunpowder.

Once crafted, 'GunPowder' could be crafted into blocks (or barrels) to be used as explosive. Or left in its item form to be crafted into firework rockets.

If crafted into "barrels", obviously its texture would be quite different from TNT.
