- SPIGOT-5732: Fix issue with spawning leash hitches and painting, by using the right block faces
- SPIGOT-6387: Allow hanging entities to be spawned mid air
- Use randomize parameter to determine if a random painting should be chosen or not
- Return BlockFace self by leash hitches entity
- Throw a standardised exception when trying to set a BlockFace to a hanging entity which the entity does not support, instead of using BlockFace south or throwing a null pointer
