Added repair beds to more vendors (Skeleton Doctors)

Patch added for those who may not have access to the portable repair beds.

Reduced required artifacts and lowered the tech level required to research the portable repair beds.
Sleeping bags are the same tier as beds, so this is a parity/qol update.

Fixed a bug making the beds not place-able.

Collapsed mesh added, new icon and desized the item.

Patched issue with the normals of the wiring (was inverted)
