ShapedRecipie builder

[kashike]

The ShapedRecipe.Builder is a bit annoying/odd to use.
Current:

builder
    .width(2)
    .height(2)
    .ingredient(2, 2, ItemStack.builder().build());

In my opinion, something like this (as seen in vanilla/forge to a point) would be nice:

builder
    .aisle("~~~", "~~~", "~~X")
    .where('~', ItemStack.builder().build())
    .where('X', ItemStack.builder().build());

Closing as there is now a PR for this. Comment on it.
