Auto restocking/withdrawing and sorting for chests.

This is a feature that I love from Terraria that I think would be awesome for Minecraft. Opening a chest gives you the option to click a button, and if you have an item type in your inventory that already exists in the chest, it will deposit that item from your inventory, or vise versa. Also, a button to sort chests for you so you don't have to do it every time you add a new item to the chest, or remove an item that creates an empty space.
