Use Leaf Litter to craft Campfires instead of Coal

The addition of the Dappled Forest and Abandoned Campsites makes this the perfect time to give campfires a time to shine as a real survival tool that players will actually want to use in the early game.

Campfires are currently something you really have to go out of your way to use as a survival tool, mainly because of the coal/charcoal requirement.

You are almost never in a situation where you have coal but no access to stone for a furnace.

The furnace already outclasses the campfire in every way as a survival tool (cheaper, portable, smelts ore, doesn't require multiple tools to fully use), except for the campfire being able to cook without needing additional fuel.

But again, you need to find coal anyway to make a campfire and coal is the most abundant ore in the game so it's not like you're only finding one per vein.

Changing the coal to leaf litter incentivizes early game usage by making it craftable before the furnace, enhances the forest-survival theme, and most homemade campfires use kindling as the starting fuel source which leaf litter is perfect for.
