Fixed AI Not Loading At Start And Enemy AI Now Attacks Player

First Update for this early prototype. I've Added a few critical AI fixes, first of which is the AI not loading at start for any ally that isn't in command of the party. Second fix is for a Closest Enemy Check, which was using AllyLayers and not CharacterLayers which the colliders are actually attached to. This caused the method check to constantly fail, causing the enemy to not be aware of player presence, and not attacking. Hopefully this'll change up the game a little bit.
