moved player package, added ArmorStand class and added DataWatcherItems in entity classes
The player package is now in the livingEntity package. Same with the LivingEntity class and the CreatureEntity class. The new ArmorStand class is also there.
You can now create DataWatcherItems for the PPOEMetaDataEvent easier than befor. In the entity classes are therefore new Methods. They are static and begin with "getDW".
