This utilizes the official SHACL vocabulary for validation report results. I had to augment the official vocabulary with f:expectation, as I think that's a very useful part of the validation result.

I also added support for user-specified severity and message keys on the shape, according to the spec.

While updating the test expectations I restructured multiple tests to allow the data and the expectation to live adjacent to each other.

@aaj3f If you've got any thoughts about how errors should look, this is a great PR to discuss them on.
