Hotfix rerendering spam - Outliner and Promptbox (#547)

Could be done better, but this works just as well under time
constraints.

For future reference: The freecam movement speed logic should be moved
to React land instead of processing the update every frame using the
time delta. Just use performance.now() in a useEffect or something.
