Try to improve consistency

- Makes code formatting more consistent with the C++ codebase. Probably removes some trailing whitespace. Maybe it would be best to commit an Eclipse or IntelliJ code format preferences file?
- Removes obscure suppressions. I personally think it's better to only suppress warnings that javac complains about. Suppressing a lot of non-standardised warnings (many of them turned off by default even in IntelliJ) just creates needless clutter.
- Fixes some trivial warnings instead of suppressing them. serialVersionUID is sort of stupid, but I'd rather mentally ignore it or just fix it if it's really that annoying.
