fully adjustable spot lights or more spot light options

right now, spot lights can be mounted onto horizontal surfaces only. This rules out scenarios like

• lighting up features above the roof of the base
• lighting up the area below a moon pool

I can see four ways to enable these usage scenarios:

1. provide a dedicated spot light shining up and down respectively
2. improve the exterior base lighting, turning it into a second, wall-mounted spotlight
3. allow spot lights to be mounted on vertical surfaces
4. make spot lights fully poseable (would probably require some build UI rework and a new model)
