[0.14.19] Steel furnaces don't make sound when opened

[jab416171]

When clicking on a stone furnace, it makes the "Inventory Open/Close" sound effect. Steel furnaces do not make this sound. This is on a multiplayer game (headless server), but I doubt that's the cause of the bug.

Cause of the bug: Steel and electric furnaces are missing open_sound and close_sound (and repair_sound and mined_sound) from their entity prototypes.

I don't know if it's an actual bug or not maybe they were made that way on purpose?

Why would stone furnaces have the sound effect but steel/electric furnaces don't? The sound should either be added to steel/electric furnaces, or removed from stone furnaces.
