1.12 adds "glazed terracotta" blocks, with bright decorative patterns; these are created by re-firing "stained clay" blocks (now renamed to "terracotta"). I suggest adding support for Glazed Terracotta for barrels and suchlike, possibly by re-firing the standard clay barrels as a parallel to the process for creating the actual glazed terracotta blocks.

• If you can re-use the resource location for the minecraft textures, this would keep compatibility with texture packs.

Closing in favor of #26

Weird thing about terracotta is it is intended to be rotated, so the barrels would always look like half a texture. Plus, I already have 70 different barrel blocks counting extensions and unfired...
