The "Unequippable:true" NBT tag on badges and badge cases does not currently work correctly.
When on a badge, the badge can still be worn by placing it in the chest armor slot.
When on a badgecase, it can still be worn by placing it in the chest armor slot, but also prevents the badge case from being Registered by the player (The "Register" button is gone in its UI).

To reproduce:
- /give Mike5357 pixelmon:bluebadgecase{Unequippable:true} 1
- Notice the badgecase cannot be registered and can still be equipped by normal means.
-/give Mike5357 pixelmon:rainbow_badge{Unequippable:true} 1
- Notice the badge can still be equipped by normal means.
