Update the morechests textures to the latest minetest_game chest texture

Along with replacing default:wood in their crafting recipies with group:wood
Textures all look good, and the code seems to work fine.

If you would like me to, I could change the textures in the money mod, but I think you are phasing that out?
I don't think there is any point in changing the textures of the bitchange mod, as that has unique textures.
