(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
- 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)
- Abstract Messages into two layers: the top layer 'Messages' is how Messages can be retrieved and sent as before. In the background, package-private, MessagesManager actually does the file read and worries about I/O while Messages takes care of higher-level things (such as joining two lines or checking the current language).
Replaced many classes to use Wrapper to get singletons and replaced the test setups to use the WrapperMock instead of setting fields through reflection
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"
