Added AI to the game fianally!

A feature that was originally planned to be in the game is finally here!

I also fixed some other bugs with the game such as,

Players being able to phase through walls in the elevator and all of the walls in the building (hopefully), flashlight not able to be refilled if you had batteries to refill it, and finally I fixed the black monitor problem on the windows build of the game!

If anyone finds any other bugs in the game please make sure to let me know, It's a great help!
