Issue on Input Shape of network

[taiharry108]

For the several networks in the build methods, the width and height may be of the wrong order.

Right, in the code we're supposed to have height before width for our data, but sometimes in q_network.py the width is listed first. But since we usually assume the images are square it's not too bad, though it might be nice to have height before width be consistently used for clarity.
