A few minor cleanups #1013

Just a few small cleanups I made going through the files. I also noticed in test.py, the generate_legal_moves function of MockBoard has a yield right after a return. I tried removing it, but then the checks gave me errors.

Thanks!

Any yield in a function makes it a generator, so return; yield is a trick to create an empty generator.
