Fixed exmaples configurations

[ZappaBoy]

I hope this can help:

• Added pygame as requirement and upgraded requirements;
• Fixed wrong logger configuration in mountain_climb_run.py;
• Fixed performance warning in mountain climbing and pole balancing config.py:

  pytorch-neat/mountain_climb_run.py:32: UserWarning: Creating a tensor from a list of numpy.ndarrays is extremely slow. 
  Please consider converting the list to a single numpy.ndarray with numpy.array() before converting to a tensor. 
  (Triggered internally at  ../torch/csrc/utils/tensor_new.cpp:210.)
  input = torch.Tensor([observation]).to(c.MountainClimbConfig.DEVICE)

P.S.: Nice and clean NEAT implementation.
