* #1874 Introduce individual ConsoleLogger instance per class
- Create ConsoleLoggerFactory from which a separate logger can be created for each class
- Allows to support individual log level settings in the future
* Fix CodeStyle issue
* Replace full class name with import
* Update usages after merge from master
* Add IPv6 support for isLocal checks
* Replace magic values like 127.0.0.1 and use our utility
* Support for IPv6 local adresses in IPv6 only or dual stack environments
* Loopback [::1]
* Site-Local fc00::/7
* Link-local fe80::/10
* Introduce extra method for loopback addresses
* Use public IP for passMaxLogin check
* Use non-local IP addresses in test after change in verification
* #1497 Throw dedicated exception for invalid YAML files and handle it on startup
- Wrap SnakeYAML exceptions when loading config.yml and commands.yml on startup into own exception type
- Handle exception type on startup with specific error message
* #1497 Fix inaccurate JavaDoc comment
- Create method to check if email is empty or the default AuthMe email (avoids repetition)
- Check that input email has '@' inside text (relates to #1105)
- Checkstyle config: allow todo comments with issue number
- Create consistency tests across all classes, ensuring: unique class names, users of expiring collectors implement HasCleanup, non-private fields are only constants
- Fix tag replacement in PlayerListener for {DISPLAYNAME}
- 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
- Move check for restricted user into validation service
- Keep restrictions in a map by name for fast lookup, avoid splitting Strings on every call
- Gracefully handle case when entry does not have the expected ';' and log exception
- AsynchronousLogin: call common permission methods through CommonService instead of PermissionsManager
- CommandManager: remove superfluous replacement of %p (handled by lazy tag replacer)
- Remove unused method in CommonService
- Create DebugSectionConsistencyTest
- SendMailSSL: Enable debug output if AuthMe log level is set to debug
- Add Utils#logAndSendMessage and replace existing, separate implementations
