Over-eye hair improvements

-Long Over eye looked like two different hairstyles layered on top of each other when it was made, giving it a weird spiky look around the face area when seen from the side. I've completely redone the side sprites.
-Regular Over eye had inconsistent side sprites which made it look a lot longer than it should.
