Title: Introduced response error hierarchy

In order to be able to distinguish between types of error more easily, an error type hierarchy was introduced. The response itself is embedded within the errors with helpers for accessing the status and body more easily.

This also introduces a special case for 401 Unauthorized. 401 should be the only breaking change as this is the only status that had its message altered.
