Title: RFC: Collect all ConfigErrors, rather than raising an exception at the first error.

Instead of directly raising config.ConfigErrors, code should instead call config.errors. In the case that this is called during config, the errors will be collected, and reported at the end. At any other point, an exception will be raised.

This still needs some tests, and the documentation needs to be updated.
