- Changed all normal results to ok.
- Normal results were intended for tools that produced info and
weren't expected to have problem results.
- Ultimately not worth distinguishing from tools that sometimes
show problems.
- One less color status makes the summary table simpler.
- Also changed the not-applicable status color to the lighter grey
that normal used to have.
- Made the success status non-configurable since ok status is the
only sensible status at the moment.
