Soulstones into possessed items

[FunnyMan3595]

What Does This PR Do

Soulstones can now create possessed items by using an occupied soulstone on (almost) any item.
When a possessed item created from a soulstone dies, it will revert to being a shade, as if it had been released from the soulstone directly.
Certain possessed items can now read, and a few can write as well.
Pressing your "use held item" keybind while a possessed item will use the item.
Committing suicide with a soul stone stuffs you into it.
Using an empty soul stone in hand will give a custom suicide prompt.
The chaplain's mysterious old shard is no longer single-use.
Many possessed item bugs have been fixed.

Why It's Good For The Game

More content for the chaplain, and RP opportunities with crew turned into possessed items.

Testing

Lots of shoving spirits into and out of possessed items and using them in various ways.
Purified and corrupted a soulstone with their respective methods.
Took a body into the soulstone and made a construct.
