Async, naming and refactoring

Breaking changes:

• Domain repositories, domain event brokers, domain event handlers and unit of work are now asynchronous by default.
  • Synchronous methods have been removed to embrace simplicity.
  • The only exception are domain event handlers, where new abstract base classes for both synchronous and asynchronous handlers have been created. The domain event handler interface is only asynchronous.
• ApplyEvent method in AggregateRoot has been renamed to AddEvent to reflect the functionality better.
• Some return types have changed from IEnumerable to IReadOnlyCollection.
