P0-B4: Part 1190: Debugging, Improvements

I have added support for random NPC’s and item spawns, etc, to the randomly generated buildings.

This is a significant improvement over the existing system.

I have also fixed several bugs, and made several minor improvements.

Interactable items, such as hackable items, turrets, etc, can also be randomly placed, and enemy AI can be randomly placed too.

I have also started preliminary work on the road network. This will require several improvements to the random generation system, but it seems to be at least theoretically possible.
