LootTable API & Replenishable Lootables Feature

Provides an API to control the loot table for an object.
Also provides a feature that any Lootable Inventory (Chests in Structures)
can automatically replenish after a given time.

This feature is good for long term worlds so that newer players
do not suffer with "Every chest has been looted"

API and Event added to control the Auto Replenish feature for players.
