port vanilla textures for ingot/nugget/block in E9E

Hopefully this won't cause me any copyright issuess.

This PR ports textures for vanilla ingots/nuggets/blocks in E9 back to E6, to makes them looks more consistent when placed together with EE items.

I'd rather leave the textures as is to be honest, to not mess too much with existing worlds/builds.

Edit: but thank you for the effort regardless! 👌

Got it!
