fix issues relating to nested inventories
fix plus sign position not updating when the parent inventory is repositioned

use ForcedAutorun instead of Autorun
forgot to remove my config from last release

fixed bug where icons would not resize when a container is moved to an inventory with a different slot size
fixed (very small) memory leak (cache is now cleared on roundStart and roundEnd)
