As most who are aware of the veterancy plate know, it currently covers
the _entire_ front of the face, making it seem impractical (if not
physiologically incompatible) and the butt of many jokes. This PR adds a
less invasive alternative, makes both a variant of the integrated
medical HUD to make it more practical, and adds unique versions for
Vaurca Workers/Warriors, Bulwarks, and Skrell.
