Implement in-memory repositories, XML load validation, and menu exit/list commands

- Add generic Repository<T> interface; EventRepository/UserRepository extend it
- Implement InMemoryEventRepository/InMemoryUserRepository backed by ArrayList
- Rename XMLLoader to XMLLoaderV1, add LoadValidator and mapper/v2 package
- Add OrderBookTradingMechanism
- Add User(String, int) convenience constructor
- Add ListEventsMenuCommand and ExitMenuCommand, isExit() on MenuCommand
- Menu now sizes selection range by max command index and exits on isExit()
- LoadFileMenuCommand reports validation issues on failed loads
- Untrack test-data/ and config.properties from .gitignore
