After crafting a cake, you lose all your three buckets

As in Minecraft PC does, when a cake is crafted you get the three buckets you used back.

But in 0.7.0 after you craft a cake it takes all the ingredients including the buckets, this is really bad to the player because it takes 9 iron ingots to make one cake, that makes it really expensive.

Steps to Reproduce:
1. Craft a cake
2. It uses the egg, the three wheat, the two sugar and the three milk buckets (with the buckets)
