Maintain speed / rotation

It would be cool to walk around the interior while the exterior is slowly flying. It should be possible to make the TARDIS maintain speed after leaving third person.

It's something I've always wanted to do with maybe basic object avoidance, would be pretty neat and make things like VR a lot better too

I've thought about adding a "plot course" feature before, where you define points to fly to and the TARDIS moves to them. As it reaches one it goes for the other. It could work for starters, then we could try to add pathfinding and obstacle avoidance

Could integrate well into the destination view that @francodml

I've split issue #576 with more complicated behaviour from this one
