## About The Pull Request
Firstly, this var was on `/mob`, even though only `/mob/living` and
`/mob/dead` could have ever used it, so who knows how much needless
memory it was consuming on stuff such as `oranges_ear` that would never
ever ever use something like this.
Edit: okay instead of memory it just polluted variable edit windows for
all /mob when it didn't need to. I like having a slim VV window
Secondly, it's a technical improvement over the previous system as we
are able to "track" where a suicide originates from, and how we can
track that from mob-to-mob-to-mob. Previously, the boolean `suiciding`
would only inform us if they had ever been connected to a mob that had
ever committed suicide, but now we are able to precisely determine which
mob gave them the trait that they must now apparently bear until the
round restarts.
## Why It's Good For The Game
Less memory usage, more indepth ability to track suicides in case you
really need that dexterity. Currently no implemented code could benefit
from using it, but it would be pretty neat if someone could figure out a
way to have someone be guilt-tripped whenever they look into a mirror
and seeing the reflection of their past life? This PR won't actually
help you code that and it'll probably require a bit more work, but it's
a possibility of some cool interactions you can do when you have this
information available to you.

## Changelog
🆑
refactor: Some aspects of how we track suicides from your living mob to
your observer have changed- please do let us know if anything has broken
via a GitHub Issue Report.

There's probably some technical improvements that can be made in some
parts of the code I reworked to accommodate this change, do let me know
if you spot any easy ones (or fuckups). a lot of excess comes from the
fact that any step in the TRAIT framework trusts that you are passing in
a valid datum (or subtype) so that's a thing
Loosely adapted from /vg/. This is an entity component system for adding behaviours to datums when inheritance doesn't quite cut it. By using signals and events instead of direct inheritance, you can inject behaviours without hacky overloads. It requires a different method of thinking, but is not hard to use correctly. If a behaviour can have application across more than one thing. Make it generic, make it a component. Atom/mob/obj event? Give it a signal, and forward it's arguments with a SendSignal() call. Now every component that want's to can also know about this happening.
