P0-B8: Part 1423: Debugging, Improvements

I have made some improvements to the artificial gravity system in the game.

There was an issue when the player landed on a small, non-spherical stellar object (Such as a small asteroid or a space station, etc), where the gravity vector would point them toward the center of the object, but this wouldn’t be the correct up vector.

I have made huge improvements here, although there is still a very minor glitch that occurs when the gravity vector updates itself.

It is possible for the player to walk all the way around an object with the gravity and upvec still being correct all the way around, which is a vital feature in this project.

I intend to make use of this much more in future parts of the project.
