Feature description
Allow the player to link their backpack to a chest. The chest and backpack are linked similarly to how an ender chest would be.

• if the chest is destroyed the backpack just goes back to being a normal backpack unless it is linked again.
• when the chest and backpack get linked, chest expands or contracts the amount of rows to fit the backpack.
• if the chest is destroyed items that were in it go into the backpack instead of dropping on the ground. (maybe make this optionally disabled in the config)
• if the chest is destroyed notify the player with a small message in the chat.
• command might be something like '/backpacks linkChest' and can be executed while looking at the chest to link it.

How the feature is useful
Say you are mining and your inventory & backpack get filled. If the chest that the backpack is linked to has a hopper that takes things out and into a storage system for example, then you can keep mining not needing to worry about going back and forth every time you fill your inventory saving (possibly) large amounts of time for the player.

Please feel free to ask me more about it.
