crafty crafts

This data pack add and changes two crafting recipes

1. The cobweb I never liked the way you get cobwebs from a mineshaft Instead, I change it so five strings make 4 cobwebs, which makes them renewable
2. wooden stairs There is no woodcutter in the game, so I made the crafting recipe actually accurate, making three pieces of any wood kind make 4 stairs. I did this because you can chop up three blocks of wood into stairs and make the cutoffs into another one
