VMSolidus a802b48e2a Psi Rework Part 2: Scenes From A Memory (#21736)
The next step in the Psi Reworks is here, this time adding all of the
remaining sources and applications of Psi-sensitivity and Psi-protection
that were on my To-Do list. Aside from a variety of tweaks and bugfixes
to powers, the most player-facing addition is the new Psi-sensitivity
related traits, which are High Psi-sensitivity, and Low Psi-sensitivity.
These traits modify the character's psi-sensitivity, which messes with
their interactions with psionics in a variety of ways.

All of these new sources and interactions with psionics are handled
entirely through components, which operate on the previously added
COMSIG_PSI signals.

Check the changelog file for more specific details on what all was
fixed. I've fixed quite a lot of bugs and issues with the various psi
powers.

I have actually tested this PR and verified that it works as advertised.

Datum Component System (DCS)

Concept

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.

See this thread for an introduction to the system as a whole.
