- 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)
- Move permissions responsibilities from command to permissions (remove some logic from CommandPermissions, add DefaultPermission enum to permissions package)
- Start possible interface for the future per-permission system implementations of permissions managers
- Reduce tight coupling by passing list of available commands as param to CommandHandler
- Split command processing method into several smaller ones
- Remove unfinished logic for unlimited command arguments (reason: was not implemented and not used, probably needs another way to handle it once the need for it arises)
- Create test for CommandHandler
