Make it possible to focus hidden nodes

[WeirdRubberDuck]

Adds a setting that allows focusing hidden nodes, like the solar system barycenter. Useful for debugging, especially now that the fly-to option no longer appears in the scene menu for things that are not focusable.

Before this change, there was no way to focus on these scene graph nodes to e.g. investigate where in space they are located, without adding another node that is rendered on that spot or changing the settings for the asset.

I also added a new component to render paragraphs of text consistently. We do this in quite a few places when the translation file includes a list of texts

Note that to see the hidden objects, the show non-focusable mostly also needs to be set as the hidden nodes are not marked as focusable

Let me know if you don't think this setting is a good idea. I'm a bit unsure but was also frustrated by not being able to focus on these nodes (to e.g. add debug axes easily to a reference frame)
