I did but there is issue I didnt know about before with texturepacks. I put these files into core datas but if you have any texture pack installed it gets overriden by files inside it becase texture packs are loaded after core datas and override. I already found the way how to fix this but so far not published. And you can call me "sh"

Please poke me at PM if you want this fixed I try to prepare it and send it to you.
