ZombieHorde 0.6.18

First pass at using Scarecrow AI. You can opt to use scarecrows by setting the config option "NPC Type (Murderer, Scarecrow)" to "Scarecrow"

When growing hordes, attempt to spawn new members 5 times before giving up

Added config option to specify maximum horde size per monument

Fixed zombies not being targeted by turrets when enabled in config
Added support to drop multiple loot types (Kit + Random, Default + Random, etc)
Added config option to set custom names, leave empty to use default names

Fixed rock check blocking most spawn points

Possibly stop rock spawns?

Should stop NPCs spawning in stupid places... maybe?

Added permission zombiehorde.ignore to make the NPC's ignore players

Additional null checks in OnNpcPlayerTarget
Fixed info command showing 1 horde when there are none

Added config option for murderer speed modifier. Use at your own risk, AI behaviour gets weird when increasing their speed. I recommend using a small value like 0.5 or less
