Update checkstyle config and CodeClimate exclusions

- Add new checkstyle checks: require Javadoc on large private methods, default in switch, declaration order & others
- Update path exclusions in CodeClimate config to match newly renamed classes (e.g. PHPBB -> PhpBB)
  - Create consistency check testing that excluded paths exist as classes
- Fix some trivial violations
