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: three pieces of any wood type make 4 stairs. I did this because you can chop up three blocks of wood into stairs and make the cutoffs into another one

This part is only available in 1.3 3. Buttons, the crafting recipe, has always been ridiculous, one block to one button, ludicrous I set the recipe to 1:4, meaning you get four buttons for one plank. 4. Trapdoors, since trapdoors are half a door, the recipe is now 6:6
