Update manual; avoid tabs in python files; get hand_coded_defense_agent working reliably

Documentation update; fullstate test program; hand_coded_defense_agent bug

Cmake revisions; uniform nums; testing scripts - hopefully working with travis

Uniform numbers added; .travis.yml for RelwithDebInfo (see earlier re cmake); will create test script next

setup.py, README.md clarifications; HFO, python_agents_3v3.sh misc improvements; prevention of endless loop for high_level_custom_agent.py

Fixed - hopefully - other python agents from having endless loop; now may be possible to add python testing to .travis.yml
