Replaces the original red TNT block with a more Medieval or Piratey barrel. Props to zozozrobv2 (zozo-zrob on PlanetMinecraft) on Reddit for the idea, I made this one because his version doesn't have a download, only image. Feel free to use this if you want to add a crafting recipe or something, just credit zozo-zrob.

UPDATE: Added a new icon for the TNT Minecart
