(work in progress)
- Inject CommandService like other classes instead of passing it as method parameter
- Not solved: cyclic dependency CommandInitializer > ExecutableCommand > CommandService > CommandInitializer...
- Separate FieldInjection from default fallback for no-Inject public no-args constructor classes
- Make CommandInitializer a normal, instantiable service
- Add various injections instead of fetching through command service
- 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)
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"
