CraftBukkit already checks that we're not trying to copy data
back to the same snapshot, reverting this fixes the ability to
properly update non-snapshot blockstates
per feedback from @liach about a bug with vanillas previous logic
that we essentially just reverted to. complex recipes could run into
cases where a recipe that does have enough items can be unsatisfied
if the items are in certain orders, making them not truely shapeless.
this scenario doesn't occur in vanilla, but users can load custom recipes.
this improves the logic to do some sorting on the lists to improve
chances of matching the recipes harder ingredients before the easier
to satisfy ingredients.
the likelyhood of someone adding a recipe that still fails this is too
extreme to care about. i doubt mojangs implementation is perfect either.
we can improve this logic more later if we actually get bug reports on it.
Mojang implemented Shapeless different than Shaped
This made the Bukkit RecipeChoice API not work for Shapeless.
This reimplements vanilla logic using the same test logic as Shaped
