Neural Network Management Rework

I spent a lot of time reworking the neural network management to fix some issues and make it work better for my needs. I made it so the distance you move between generations adds to your fitness to an extent as if they stop moving they wont be stimulated enough to continue to evolve. I also added random colors to the AI, increased the number of AI to 20, increased the AIs vision distance by 50%, and tweaked the weights of each part of the fitness function(hits, attack count, and distance traveled) and made mutations occur less often and have less effect so that things can evolve more gradually and the AI don't go from one extreme to the other. You can also see the highest fitness value from the last generation in the top left of the game window.
