When a testcase has both a .in and .interaction, we can run on the .in but the pdf should only show the .interaction

Would be cool if we could catch some common mistakes

Could either be a standalone python script, or part of validation.h

- should write to `judgemessage.txt` and `teammessage.txt`, instead of `stderr`. Reserve `stderr` for crashes and possibly `judge_error`s. --- Less obviously good changes: - Validator object could be global -> I...

This may improve long term maintainability and give better errors during development.

Better handling of WA+RTE submissions to interactive problems.

This is occasionally useful after latex errors.
