Create the NotFoundError

[GPortas]

Overview of the Feature Request

For now any error returned by the API in a read operation returns a ReadError, which includes the message with the HTTP error code as a very simple string, but we can define a new NotFoundError that extends ReadError also including more refined data. This way we can safely identify a not found error within the block catch of the promise, and carry out the necessary actions in the SPA.
