Title: Rewrite furnace

* Move furnace related code into furnace.lua
* Move duplicated code into functions
* Rewrite ABM:
* Easier to follow strcuture (no returns in the middle)
* No unnecessary calls to get_craft_result
* Split logic and "visual feedback" (a bit)
* Fewer calls to meta:set and meta:get
* Better feedback on the current state of the furnace
