Added:
Complete Item Meta and NBT data serialization.

What does this mean?
It means spawners, books, skulls, everything should now be supported with recipe control! You can even use items made with custom item plugins!

Fixed:
- Some custom furnace inputs not updating properly when shift clicking
- XP not saving for some furnace recipes
- XP not being given for some furnace recipes
- Furnace not returning bucket for water and lava buckets
- Other various fixes

I did a lot of debugging and testing to iron out these bugs, but I'm not perfect! Let me know if you run into any problems with the update and I will fix them quickly in the morning

Thank you
