Title: PaintingItem now implements Placeable. Completes Vanilla-425

Kills two birds with one stone:
- Solves the error of placing a painting where no paintings can be placed
- Takes the painting from your inventory because of implementing Placeable

It also makes more sense for PaintingItem to implement Placeable anyway, rather than using onInteract.
