[FREE] Gravestone Mob! 1.2

Update 1.2:
- Used a different mechanic for gravestone zombie spawning, so no more console spam!
- Fixed the weird name tag issue when gravestone zombies spawned
- Nerfed Gravestone Fletchers (this fight is supposed to be possible with iron armor lol)
- Fixed Gravestone Weaponsmith strength buff

Changes:
- Made each type of gravestone zombie more unique
- Made the actual gravestone mob more distinguishable
- Tweaked some of the skills and mobs so that it is more challenging but fair at the same time
