Regenerating Ores for FFA Games

These ores can be dug and will respawn after a certain length of time. They have two forms: The ore form, and the stone form. When the ore form is placed, it will wait for the player to dig it, then will give the user the item, or, in the case of a full inventory, will be placed on top of the ore. When the ore form is dug, the stone form is placed in its place, which, if this stone form is inside of a protected area, will not be able to be dug. When the stone form is placed, a timer sets (greater for rarer ores) that, when it runs out, replenishes the ore.
