Crafting recipes for banners/fireworks

(Edit: added fireworks to title)

The crafting recipes for banners are rather complex:

http://minecraft.gamepedia.com/Banners

• Each pattern modifies the input banner and outputs a new one with different NBT data - not possible right now AFAIK
• They accept any color of dye
  • With the current recipes.yml structure, there's no way to specify that any damage value of INK_SACK is allowed but that this affects the output.
  • In the case of items like wool, this is handled by repeating the recipe 16 times, which is okayish since it's autogenerated and the recipes are simple. Definitely not ok for something as complex as these recipes.
• Most of them take banners as input in any empty slot of the recipe (that isn't used by a dye or other item). Seems like an exception to the usual meaning of "fixed recipe"

I vote for specialcasing this monster.

I'm already worknig on this. Bukkit itself has no support for this kind of recipe - ones where NBT is either used or edited. (See 'Special recipes' on trello)

I'm creating a 'SpecialRecipe' class, that includes methods for getting a result, given a set of inputs. This is similar to the way that Vanilla does it. Currently it's not just Banners that do this, it also affects Fireworks and their effects, Book and Map duplication, etc.

Oh, and tool repair as well. That's not related to NBT, but there's still far too many cases to simply deal with in a static file.

FYI, you should be able to do the static Banner recipes no problem (ie the ones with 6 coloured wool and 1 stick).
