Fixes Runtime When Creating new Humans

It runtimed because when there was
/mob/living/carbon/human/vulpkanin/New(var/new_loc)
>>>>>var/obj/item/organ/external/head/H = get_organ("head")
>>>>>H.h_style = "Bald"
>>>>>..(new_loc, "Vulpkanin")

in human/human.dm, it'd error out because the mob doesn't have those
organs at this point-- so I just moved the definition of what hair/head
accessory styles these basic default mobs get to the species definition,
where it'll accomplish the same thing as it used to while still using
the head-hair system appropriately
