Added several more functions to pre-existing classes:

-Spawner, Transport, Healer, Guard, Bard jobs received more functions.
-Added more functions to the transporter role.
-IRole: Added getNpc() function.
-IAnimal, IEntityLiving, and IEntityLivingBase received more functions from their MC counterparts.
-Nearly every function with that takes position/vector parameters now has an equivalent with IPos as a parameter instead.
