- Change interface to use (CommandSender, List<String> arguments)
- Use CommandArgumentDescription#name instead of "label" (to prevent confusion between command labels and arguments)
- Simplify command difference computation in CommandHandler (no longer consider argument difference)
- Remove one of two unnecessary constructors in CommandDescription (in favor of the builder)
- Remove TODO about unlimited arguments (not currently a priority, will create a story instead of leaving a dangling TODO for ages in the code)
- Create Initializer class that only initializes AuthMe commands
- Move remaining method to CommandHandler
- Deprecate constructors on CommandDescription in favor of the builder
- Various cleanups and comments
- Add tests to check the integrity of the commands that are defined in the CommandManager
- Convert some more commands registrations to the new Builder format
- Create builder class for CommandDescription
- Remove redundant methods in command registration classes (e.g. certain validation is superfluous because we only instantiate the classes internally)
- Replace multiple occurrences where a field is directly instantiated e.g. with a list and then its value is overwritten by a constructor = redundant instantiation of objects
Minor refactorings in the command section for familiarization.
1. Removed suppressWarning("Deprecated") - the method is deprecated for a reason and we should be made aware of that.
2. Removed same javadoc on ExecutableCommand implementation that just had the same as the interface (this is just clutter; @Override signals that it's an implementing class and a developer can view the superclass javadoc)
3. In places where the AuthMe instance was retrieved at the top but used at the very bottom, moved it to the bottom to reduce its "scope"
