Issue Description:

I want to change some alloy smelter ingot recipes to make the game harder but my problem is that the old alloysmelterrecipes_core.xml still remain. Is there a way to delete old recipes in the ender io machine configurations like "AlloySmelterRecipes_User.xml".

What happens:

The old recipes remain even though i want the new ones to take their place. I tried to use the old recipe to make electrical steel and it worked.

What you expected to happen:

That the new recipes overwrite the old ones.

Steps to reproduce:

1. Change Electrical Steel recipe in AlloySmelterRecipes_User.xml lto this.
