I don't care if someone sets a recipe with an orb level greater than the max, that's their fault, but if they accidentally set one to 'tier 0', i don't think nei should crash.
Just added a break so that the for loop when going through the items when searching uses, exits when it has found the ingredient. This fixes the bug where searching usages on an item that's used up more than once in a recipe results in multiple copies of the recipe.
