P0-P-172: Part 85: Long Distance Travel, Debugging

There is still an issue with the long-distance travel system.

Unity seems to freeze when I travel at high velocities, although everything seems fine at lower velocities.

I have investigated a number of potential causes for this. I thought it might be caused by the number of objects that I am trying to move (I have a complex scene, whereas the SEE demo scene has almost no structures, just some planets), but the freeze issue occurs even with no other objects in the scene.

I suspect that this must be collision related, the ship may be colliding with an object at very high speed, which could be leading to errors in the physics calculations. This will need to be fixed as soon as possible.

I have also spent some time debugging some old errors that were present in the console. There were mostly simple fixes, and were fixed by adding some safety checks to ensure that objects existed before being accessed, etc.
