this is mainly helpful for the Material farmer for farming Happiny dust.
changed the default sandwich to the normal (non-shiny) sandwich, so users don't accidentally use up Herba Mystica when they weren't intending to shiny hunt.
if there is a need for to add non-shiny encounter sandwiches for the rest of the types, I can add them later. But I don't see a use for them at this time. So, right now, the BaseRecipe::non_shiny is basically hard-coded to SandwichRecipe::non_shiny_normal.
