config.yml:

mob-equipment-tier   :  3  
rabbit-always-killer   :  true  
ghast-invisible   :  true  
creeper-always-charged   :  true  
enderman-always-agressive   :  true  
villager-always-nitwit   :  true  
pigman-always-agressive   :  true

bed-explosion   :  true  
deadly-drowning   :  true  
deadly-fire   :  true  
animals-turning-into-wither-chance   :  0.25

Most of the configs already speak by itself, but i'll explain some of the more confusing ones:

mob-equipment-tier: It affects the mobs armor and Sharpess/Power, Sharpess/Power = Tier + 2(Max 5) and the Armor is Tier 1 = Gold, Tier 2 = Iron, Tier 3 = Diamond(Default)

animals-turning-into-wither-chance: It's the change of any animal turns into a wither when you get close to then(Yes this is a feature) the chance is in decimals, so 25% chance = 0.25

This is my First "Serious" Plugin so it will have bugs, so please report them at the comments and i'll fix asap
