P0-A6: Part 731: AI, Dynamic Story

I have added several actions and new features to the AI system.

The AI can now use the new dialog system to interact with the player. Their dialog will change depending on various events and variables, such as whether enemies are present, the temperature, weather, and what the state of the current story or objective is.

They can also help the player by healing them, or offering them ammunition, etc.

I have also made improvements to the AI for the creatures. Not only can the player now damage them with a weapon, but they will respond to non-fatal damage by either running away, or attacking, depending on whether they are prey animals or predators, and depending on their current health status.
