P0-B7: Part 1361: Debugging, Improvements

I have completed the next phase of testing with the AI.

There were some bugs and issues and unsupported behaviour, but it has gone very well.

The code seems quite solid at this point. The AI can enter buildings, and carry out actions autonomously within those buildings. The AI state is also stored persistently between game sessions.

There are still some features that I need to add, and some more work and tested needed.
