Subject: [PATCH] SPIGOT-227: Add entity persistent flag

Non-persistent entities won't get saved when the chunk saves the entities.
Entities that are passengers of a non-persistent entity won't get saved.
Players won't save their vehicle, if the player is directly or
indirectly riding a non-persistent entity.
