Bed Updates (#2389)

## About The Pull Request

**Makes ~~roleplay~~ double beds craftable
All beds and bedsheets now have E/W Dirs**
![Buildable Doublebeds and DirBeds supported
too](https://github.com/shiptest-ss13/Shiptest/assets/33048583/2c3bb916-6996-4eb0-9d08-31319824d6fb)

## Why It's Good For The Game

Consistency. Double beds and doublebedsheets had dirs but this hadn't
been carried over to single beds and bedsheets. I was then asked by one
of our lovely spritainers whom I don't know the gitID of to make Double
Beds craftable.

## Changelog

:cl:
imageadd: All forms and beds and bedsheets now have directional sprites.
code: Made Double Beds craftable at the request of Rylie. Have fun with
that.

your name to the right of the first :cl: if you want to overwrite your
GitHub username as author ingame. -->
<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
