Server-side Viking Helmet Creation System

[Spartan322]

Allow json to be created to generate craft-able helmets, current planned syntax:

{
   unlocal_name: "<name>",
   model_name:"<model name>"
   # overrides texture_name in 1.8, applies as texture_name in 1.7.10 (if texture_name is missing) 
   texture_name:"<texture name>" 
   # overrides model_name in 1.7.10, applies as model_name in 1.8 (if model_name is missing)
   worn_model_name:"<worn name (obj)>"
   # doesn't render if not declared, may eventually support json model (first iteration shall not)
   recipes: {
      {
         ["ABA","AAA","AAA"], # custom recipes types not natively supported
         A:"minecraft:block_dirt",
         B:"<modid>:<item name>"
      }
   }
}

This shall be an experimental feature
