Pumpkillager's Quest

Added config option to determine chance of Pumpkillager spawning when a pumpkin is broken, by default 0.1.
The pumpkillager won't spawn anymore when another one is already nearby.
The pumpkillager will only spawn when the pumpkin broken is free, e.g. with air blocks around and above. To prevent it spawning inside a "pumpkin structure".
