Relighting to Night

I've updated my project to re-enable the dialogue system and improved the AI to stop when the player approaches, so conversations can be started. I've also re-lit the scene to be a spooky night scene, added an options menu to address performance issues, and temporarily removed the bio mutants. Next steps are to build a scene from scratch, continue to iterate on the AI, and build out a conversation trees for the robots and human NPCs.
