- 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
- 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)
- 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
- 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
- Create test to ensure that commands don't define the same binding
- Create stricter attribute validation in builder: throw an error if required field was not initialized
- 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
