(work in progress)
- Pass all dependencies via constructor
- Encapsulate command handling more (e.g. split CommandHandler with new CommandMapper)
- Add help command to all base commands at one central point
See AccountsCommand or HelpCommand for an example of the advantages - all necessary functions come from CommandService; objects aren't retrieved through a singleton getInstance() method anymore
- Fix bugs in behavior (wrong labels being shown for help)
- Change order of labels and arguments in FoundCommandResult constructors
- Move FoundResultStatus enum to its own class
- Create test class for HelpProvider
- 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"
