Code effeciency project: HUD items rewrite

Before: Every tick each HUD item would recalculate and redo images for every mob in view. For items like the secHUD where we're transversing implants and the various records this gets very expensive. After: Mobs use their hud_list variable to store varius huditem images, when conditions change for those specific huditem images it updates the specific ones on demand. As a backup every 30 ticks or so the mob will update all of their hud_list. Also: moved proc/RoundHealth() from 2 seperate locations into __HELPERS/mobs.dm Conflicts: code/__HELPERS/mobs.dm code/game/objects/items/weapons/implants/implanter.dm code/modules/mob/dead/observer/observer.dm code/modules/mob/living/carbon/human/human_damage.dm code/modules/mob/living/carbon/human/life.dm code/modules/mob/living/living.dm code/modules/mob/living/living_defines.dm code/modules/mob/living/silicon/silicon.dm code/modules/virus2/helpers.dm code/setup.dm icons/mob/hud.dmi
