That should be part of problem_content, since it is versioned, and (for
things like template-based solutions) can
also be translated.

BTW, I think we need to change problem table names from topic_problem*
to problem_list, etc., since
problems can be linked to other objects (tests, contests), or be
completely stand-alone.
At least it'll be possible in future.

Another (purely cosmetic) thing, I just noticed, is that we have
_contents tables, while
it should be _content.
