## About The Pull Request
I may have forgotten a return which was overlooked in reviews, and
get_embed could fail if an object without an embed_type (shrapnel) got
assigned embed. Also optimized generate_with_values to not recreate the
datum if its not the "default" one.
## Changelog
🆑
fix: Embedding now properly changes its values.

## About The Pull Request
This refactors embedding elements to make them use singleton datums
(similarly to armor) instead being bespoke and creating a new element
every time armor values are supposed to be adjusted.
Default values have been removed from defines due to now being declared
in base class itself.
Additionally fixes vending machines and tackling gloves setting
generated shards (which they instantly embed into their victim) embed
properties to null after running the embedding code, despite said shards
having non-null embedding values by default, making them not be able to
embed into anyone else, also potentially breaking the pain/jostling code
if they somehow get updated.
## Why It's Good For The Game
Current embedding system is an unnecessarily complicated mess as bespoke
elements are hard to work with, and creating a new element every time
you change values is hacky at best. This change should make it easier to
read and work with.
## Changelog
🆑
fix: Fixed glass shards generated from falling vending machines or
tackling windows not being able to embed into anyone.
refactor: Refactored embedding code to use datums instead of bespoke
elements and ugly associated lists.
