Refactored cInventory to use cItemGrid for the actual Storage 

This makes the API more orthogonal and is easier to use in the plugins. Also changes in the inventory are now propagated to the needed places (armor updates to BroadcastEntityEquipment etc.) even when the inventory is changed by a plugin.
