Remove Python main idiom and add coding conventions to README.md

I realized I don't need this stupid `__main__` convention anymore because my
build system always calls Python programs like `python -m main`, so I just need
to have a function named `main()`. I also started adding some general coding
conventions to the README and fixed a typo.
