P0-B2: Part 1074: Improvements, Debugging

I have been making extensive improvements to the AI in the project.

Firstly, I have added the Ability for AI to spawn within randomly generated buildings. These I enemies are programmed to defend static locations, instead of patrolling around like the existing AI enemies.

I have also added arc of sight and line of sight checks to the AI, in addition to a lot more features that substantiallyimprove the capabilities of the AI.

It is now possible to sneak past the AI by hiding behind objects, or approach from the rear undetected.

I am also working on fixing a number of bugs, and making additional quality of life improvements.
