Comment format changes.

- Collapsed Javadoc comments for all fields.
- OsuFile now has proper Javadoc comments.
- Fixed various mistakes with comments.

Some changes with enums:
- Changed Class.values() calls to values().
- Changed size() calls to a SIZE field.
- Changed valuesReversed() calls to a VALUES_REVERSED field.
- Removed 'static' from enum declarations.
