ZenXArch's Zombie Apocalypse

Added lots of new config options

• optionally showing difficulty in player subtitle (debug.toml) time period through which difficulty varies (time.toml)
• enchantments (equipment.toml)
• biome checks (spawn.toml)

Changed logic for several factors

• spawning, now picks an initial pos and tries spawning extra around that
• Now uses #swords #axes #{mace,trident,{head,...}_armor}_enchantable weapons/armor
• Changed chances for picking weapons (lowered it, ~0.5 chance for any single piece on a zombie)

Fixed bugs (I don't know which ones, or even new or old ones but they were fixed)

I basically went full quality control and like tried to over engineer I think (add too many locs/ so maybe more bugs)

Performance might get worse.
