P0-B5: Part 1275: Debugging, Improvements

The AI navigation and pathfinding is going well.

The AI can successfully travel on the elevator and generate and transition to the interior graph.

I had some issues with the AI being able to properly interact with interior objects, but this has been fixed now.

I have also added the ability for the AI to open doors, etc, as well as fixed some issues with the AI’s upvector and movement.

The interior transition for the player has also been added, and I have improved the placement algorithm for the apartment block in the city.

I have also added persistence to the system, so that if the player saves while in a building, the AI and interior transition settings will be stored when they load again.

It is also possible now to purchase individual apartments within the building, and have this stored on the server persistently, so that this apartment is always owned by the player.
