## About The Pull Request
Currently if you want to apply a HUD you usually add both its trait and
the HUD itself. Only exceptions are things like simplemobs where you
should avoid adding the hud trait since it adds security/med DB access
and such, but there is no cases where you'd want to apply the trait and
not apply the hud.
Requested by Melbert about a week ago.

## Why It's Good For The Game
This makes working with HUDs significantly easier, as you no longer have
to bother with manually adding/removing them. Also potentially removes
an edge case where if your hud could get removed while keeping the
trait.
## Changelog

refactor: HUD traits now apply their corresponding hud automatically
/🆑
This folder is full of #define statements. They are similar to constants,
but must come before any code that references them, and they do not take up
memory the way constants do.
The values in this folder are NOT options. They are not for hosts to play with.
Some of the values are arbitrary and only need to be different from similar constants;
for example, the genetic mutation numbers in genetics.dm mean nothing, but MUST be distinct.
It is wise not to touch them unless you understand what they do, where they're used,
and most importantly,
how to undo your changes if you screw it up.
