P0-B8: Part 1437: Debugging, Improvements

I have spent more time on the exterior hull base texture for the new ship model.

There are still more details, etc, to add, but the new base texture looks reasonable good.

I have also made some improvements to the interior texture, but I am still not sure how to get the required level of texture resolution.

I could use UDIM tiles, or I could use a repeating texture.
