Spawner

Decide how spawners should work

Definites:

• Spawner-Lifetime is limited in some way
• Spawners per plot are limited in some way
• Some way to get Spawners (buy, vote, craft, lucky-find item, ...?)

Possible stuff:

• All spawners have a built in spawn-limit
• Spawners get destroyed/replaced with another block if they are empty (make emptyness visible)
• Spawners can be crafted (its luck what type of spawner and how good they are; good for trading; similar to enchanting)
• Possible 'enchants'
  • Spawnspeed
  • Spawnamount
  • Spawngroupsize
  • Daily spawns
  • Plotlimit (1/1, 1/2)
• Crafting should be expensive (gold,iron,diamond + growables?; possibly other time consuming activity-items like brewing/smelting/fuel-creation?)
