Waystone visibility affects which player can teleport/interact/break what Waystone. Global, and Public is accessible for anyone, with the
waystonesplus.interact and
waystonesplus.teleport permissions, but only the owner of the Waystone, OP players, and players with the new permissions below may perform these actions on another player's Waystone

Now a crafted Waystone is Private by default
Waystone spawned by /wsp get <type> is GLOBAL (will add it as an option to change)
New permissions:

• waystonesplus.breakwaystone.private
• waystonesplus.teleport.private
• waystonesplus.interact.private

Small bugfix: When a Waystone is broken, and right after the server shuts down, the Blockdisplays of those Waystones could stay there.
