HUD traits now apply their corresponding hud automatically. Most clothing/item/etc sources of HUDs now only use traits (#84984)

## 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.

## 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.
