Title: Furnaces

(Sorry for the micro pull request!)

This fixes furnaces. Until now, moving items to the fuel slot made mineserver segfault. This was related to an uninitialized variable which was later compared to `NULL`, which isn't necessarily true, which resulted in the furnace not being created in the chunk map.

Also, the furnace code now uses the "set slot" abstraction code.
