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
