Enable Quantiles

[davidsc-unity3d]

I had some trouble getting the Quantile feature normalization running - I discovered that it had been turned off

        "skip_quantiles": True,  # Skipping quantiles helps performance in OpenAI Gym Cartpole-v0

I suggest reading skip_quantiles from the config files, and just turn it off for each of the examples.

This should be easy to fix. Give us some time.
