P0-MS5: Part 362: Debugging, Optimisation

I have found, and fixed, some issues with the floating origin system.

I have now extensively tested all vehicles and ships, the AI, and the players own avatar and they all work with the floating origin system.

It is now possible to fly, walk, or drive, either alone or with an AI entity, over vast distances, either on a planet or between planets.

There should be essentially no limit now to how far the player can travel, since everything is generated procedurally.
