Even More Coals

This is my first mod. Feedback would be nice.

This mod adds new types of coal.

Bad Coal:

This coal is more common than regular coal but smelts less items.

Better Coal:

This coal is better than both coal blocks and lava.

Super Coal:

This is the absolute best coal, and will almost always solve your fuel problems permanently, but it is expensive and rare.

(I recommend JEI (Just Enough Items) for the crafting recipies.}
