Some way of restricting stack rules to specific worlds and allow for multiple sets of rules.

I'm not sure how this is currently going to be implemented so feel free to offer ideas.

My current plan is to consolidate all of the configuration files into one in the following format:

allWorlds:
  default:
    min/max/items
  player:
    min/max/items
  group:
    min/max/items
  chest/enderChest/otherContainers
    min/max/items
world:
  default:
    min/max/items
  player:
    min/max/items
  group:
    min/max/items
  chest/enderChest/otherContainers
    min/max/items

Suggestions and critique welcome.

Edit: Fixed formatting.
