closets and its children can no longer contain a near infinite amount of mobs.
Adding a mob_size var to mob/living . All closets can still contain the same amount of small sized mobs as before(mouse, parrot,pAI, viscerator, lizard, chick), but they can no longer contain large mobs (alien emperess, blobbernaut, juggernaut, hostile tree, goliath), and they can contain a few human sized mobs (three for bodybags, two for closets and other children).
Fixing a silly typo.
Adding puppies and kittens to the small mob category.
Increasing mob_storage_capacity for closet and bodybag to 4 and 6 respectively.
Merge branch 'master' of https://github.com/tgstation/-tg-station into bodybagfix1
