Hordy Zombies

1.9.5 "Horde": twice the zombies at night, zombie archers and a Blood Moon mini-boss. No new blocks; new config sections [world], [archer] and [mutant].
- Packs: at night one extra zombie comes for every plain one near you, in packs of 3-6 (at most 24 around a player). Not on a Blood Moon and not on Peaceful. Packs leave by day. Set world.zombieSpawnMultiplier to 1.0 to turn them off.
- The Archer: a new zombie in a ragged hood with a bow. He keeps 7-13 blocks away and shoots (3 damage); a shield blocks his arrows. About every 10th zombie, and from the 2nd wave of a Blood Moon too.
- The captain's volley: "Take aim!" - a red 5x5 frame appears on the ground around you, then the archers rain arrows on it. Step out of the frame or get under a roof; a raised shield takes half.
- The Mutant: from the 3rd Blood Moon the last wave brings one Mutant per player. 200 health and a boss bar. He slams the ground, charges through walls, throws rocks and zombies at you, roars to knock your shield down, and eats his own zombies to heal. At a third of his health he rips out a bone club. He leaves at dawn.
- The Mutant Head: a trophy that stands on a floor or hangs on a wall and roars at a redstone signal. New advancement "The Mutant Falls".
- New op commands: /sz pack and /sz mutant.

Also in this file, 1.9.4 "Mercenaries":
- Mercenary Contract (20 emeralds at a weaponsmith or an armorer): hire a Crossbowman, a Man-at-Arms or a Squad Medic on a free bed at your base, up to 10 per base.
- Modes: stand here, follow me, patrol the base. Give them your own armour and weapons. They rank up from kills: novice, veteran, hero.
- They eat in the evening from a chest or barrel by their bed, or you can feed them by hand. After 3 hungry evenings they leave.
- Villagers help defend your base: the farmer brings food to the mercenaries, the weaponsmith fights back, the cleric heals you after a fight, the cartographer sells a map to the nearest nest, and the librarian warns you of a raid.
- Holy water is stronger (14 damage, the lingering cloud burns too). The ballista now hits every mob except pets, mercenaries and captives.
- The rapid crossbow is held in one hand when you carry a shield. The captain can dash at you, parry and dodge.
