Here's the clean, self-contained replacement of LSTMs --> GRUs in the A3C implementation

Everything look good with the LSTM --> GRU change? This PR is clean and ready to merge, unlike #85.

As mentioned in #85, this should be strictly faster and higher performance for all inputs across the board since it's a fundamentally better way to structure the RNN.
