KawaMood's Waystones

• Waystones now have a facing data. This data is defined by the opposite of the facing orientation of the player when it places it, the same way it does with chest or lectern.
• When being teleported from a waystone to another, entities now always end up on the block in front of the waystone's facing direction, or two blocks further if one of them had a vehicle.
• Waystones placed before this version have no facing property, the landing point direction will be "north" by default. You can still remove and place it back to change its facing direction at your ease.

Note: This change aimed to allow players to place their waystones against a wall or in tight areas. Before it, entities landed next to the waystone in a random direction.
