v3-7-5

Evaluation engine version: 3.
Model version: 7.
Decision engine version: 5.

Basically, just made the model structure bigger:
Input -> 64 -> 64 -> 32 -> 16 -> 8 -> 1.

Loss went down overall. I'm seeing numbers between 0.001 and 0.002 now.

I think I'll keep making the network bigger and see what happens. The most recent game was really encouraging. No hug blunders for 15 or so moves. It developed pretty well honestly.
