suggestions: bane of arthopods buff and small villager trading improvement

Hello,

I think what really needs a buff is the Bane of Arthopods enchantment. I think it'd be cool if it's effects applied also to more creatures, such as blaze rods, magma cubes and endermen (or more if a creature comes to mind and it amkes sense!)

Also a pretty minor one, but with the toolsmith / blacksmith / weapons smith. Make it so that the coal trading also applies with charcoal.

I don't think this'll completely ruin the balance of villager trading. But I really hope you take into consideration a bane of arthropods enchantment. 

Thank you for continually improving the game nonetheless :)
