New route for specific validation results

- Parent route (/results/validator/user/repo) loads "latest" results.
- New route (/results/validator/user/repo/id) loads results matching
"id", which is either a commit hash (from a validation triggered by a
hook) or a UUID (for a validation triggered by one-time pubvalidate).
