Add Guides on the main menu that explain the various simulation options and how they work (e.g., brain types, robot types, and environment types)
New simulation option: "Evolve activation functions", allowing evolution to change the activation functions of neurons
New neuroevolution option: "developmental encoding", an indirect encoding that creates neural networks using developmental instructions
Animats can now steal energy when they attack other animats
New neuroevolution option: "Dale NEAT", where neurons can be excitatory/inhibitory and network weights are all positive
New simulation option: "Morphic Fields", this is a population-wide evolutionary memory that is used to bias mutations
Robot performance optimizations, to make the game run faster/smoother (especially at higher simulation speed multipliers, and with larger robot populations)
Bug fixes
