As well as adding methods for ItemFrames, this moves some methods
previously contained in Painting to Hanging, as they are shared by both
classes.
An enum was added that represents rotations, similar to a clock-face.
This is needed as a contrast to cardinal direction based rotations.

Added interface to get/set the art and facing direction on paintings, and expanded painting break events to catch more cases (including fire and lightning); removed PaintingBreakByWorldEvent since it's identical to its superclass

These are place holders at the moment, to be used when determining
entity type. Further functionality could be added to these interfaces
later.
