Fixed CT 'inputs' getter, added 'nonConsumable' getter

[TheDarkDnKTv]

Closes #1439

What

While iterating recipes, in case recipe has non consumable ingredient (count = 0), it will crash. Crafttweaker has check for empty stacks.

How solved:

Added filtration of inputs, to provide only normal ingredients. Non consumables getter was missing, so I added it.

Outcome:

• Fixed CT crash on calling Recipe.inputs.
• Added CT getter for non consumable recipe inputs

ZenScript example

for recipe in RecipeMaps.BLAST_RECIPES.recipes {
  var ingredients = recipe.inputs;
}

Possible compatibility issue:

None, API changes only adds method, and fixing broken logic of one of old.
