## About The Pull Request

Converts the manual heart-beating effect of the cursed heart into a
component.
Behavior has mostly been maintained, but polished a bit as compared to
the original cursed heart. Most notably, the action for beating your
heart is now a cooldown action - providing a visual indicator of when
you can beat it again, rather than leaving you guessing. Some better
checks have also been put in place for edge cases such as having your
species changed.
Implementation inspired by the existing "manual blinking" and "manual
breathing" components. Currently only used by the cursed heart and the
(now majorly simplified) effect of corazargh.
My first component, so hopefully I didn't miss anything.
## Why It's Good For The Game
The cursed heart was kind of unusably bad - which may have been part of
the intent, but having to count in your head or spam-click the button is
just annoying. With a visual indicator of when you should beat your
heart, hopefully it will be slightly less awful for the cursed.
The real motivation here was that corazargh's implementation was kind of
a travesty - summoning a cursed heart inside of your body while it was
in your system, then restoring your old heart afterward. This was
error-prone as well as just being ridiculous. Making this effect a
component gets rid of these problems, and leaves space open for new uses
of manual heart beating if anyone feels like being cruel.
## Changelog
🆑
fix: Your heart will no longer be deleted if an admin heals you while
you have corazargh in your system.
refactor: The cursed heart has been streamlined a bit, and now gives you
a visual cooldown for when you can beat your heart again.
/🆑
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.
