[Puzzle] Spawning: Position, Orientation and Fancyness

[sauterl]

The puzzle is currently spawned at a fixed, arbitrary position.

It should be changed in a way, that the puzzle spawns

• in the middle of the wall of the source image
• size / 4f in front of the wall
• oriented to have the same orientation as the wall (e.g. by using WallAnchor as a parent)

Further fancyness can be added by teleporting the player into the center of the room / in front of the puzzle and use the (new) Fade to fade in and out of the puzzle mechanic.
