Changes

- The drum is no longer sold in a shop, it can be found in random orc loot

Added interaction to most beds. This is just something I'm playing around with. I think it'd be nice if beds had a use in the world, maybe to fix certain ailments or something like that, but right now beds just give out Comfort buffs, the same as the ones given out by Carpentry-made chairs. (So this is a reverse-nerf to carpenters, technically, but those chairs need improvement in the future anyway, at least in buff duration.)

There is still no lie-down animation, so you sleep in a sitting position for now.
