Modding: Allow disabling/removing vanilla recipes

[jlai]

Right now (9.4.x), there doesn't appear to be a good way to remove or disable vanilla recipes from the game short of copying & pasting the entire item cs into a .override.cs -- which is quite fragile, especially for mods intended for distribution.

ModsPreInitialize/ModsPostInitialize allows tweaking some of the recipe options but there's no way to skip the calls to Initialize and CraftingComponent.AddRecipe or remove a recipe from a crafting object (also meaning the crafting component can't be customized this way).

I'm thinking the default template constructor could be updated to something like this

this.CraftingObject = typeof(RockerBoxObject); // allow overriding

this.ModsPreInitialize();
if (!this.Recipes.Any()) return; // don't register recipe family if all recipes removed by mod
this.Initialize(Localizer.DoStr("Gold Concentrate"), typeof(GoldConcentrateRecipe));
this.ModsPostInitialize();
CraftingComponent.AddRecipe(this.CraftingObject, this);

There probably also needs to be some tweaks to whatever this code is doing, to skip empty recipe family classes:
