Real Big Backpack

A 12 slot backpack to replace your toolbelt, but can hold much larger items. The first 9 slots hold small items, and the last 3 hold medium and large items. (So also crates, railgun shells, ammo boxes etc) To try and avoid infinite storage, the backpack can not be stored normally, and must be placed on a shelf like a crate. Can be crafted using 4 organic fiber in a fabricator. Internal name "backpackbig"

This mod does not have any downsides to using this backpack, which makes it much much more powerful than vanilla. This is intentional.
