[Feature] Test/Validator sorting


When creating a new CoC or Puzzle, wouldn’t it be nice to be able to easily sort the tests/validators, or add new tests/validators in other positions than the last one?

It seems pretty common to write a series of tests and validators, and to feel like you miss some specific ones early on. Moving each test/validator pair one by one to add a new one at the beginning is kinda painful ; why not being able to organize them afterwards?
