pack advance

hi!!

I have updated some things (because I started to experiment with something but I see that it didn't work XD) in short I changed some textures like:

. raw-iron
. raw-copper
. raw-gold
. amethyst_shard
. copper ingot
. charcoal
. coal
. golden_apple (color setting)
. redstone (layout readjustment)
. gunpowder

anyway that's all I hope you like the changes (maybe I keep changing new things)
