Version 1.1.3

Another day, another update - I'm seriously considering making a sequel...

The Changes in 1.1.3 are:

1. Made Creatures' Colliders SLIGHTLY smaller, so they don't block each other as much
2. Added a new Input Neuron - Movement Direction - this is set dependent on where the Creature is/was moving
3. Made the Creatures use the ReLU activation function again, since it does perform better
