Passive Light Upgrade

[penturt]

Couldn't think of a better name, but in short an upgrade that would add a slot to the backpack that would let you place a light source block/item (torch, lantern, frog light etc...) into it and it would emit light around the player. Maybe also render the block/item as if was on the backpack.

The goal is to free up a slot and not having to actively hold the light source in hand to emit light.
