Implemented as part of #728.

Should we also change https://github.com/DMOJ/judge-server/blob/master/dmoj/cptbox/isolate.py#L45 to `List`?

Implemented by #1645.

Superseded by #1105.

As an example, ```yaml problem_storage_root: - 2: /problems/ccc/nccc - 1: /problems/apio - 1: /problems/bbc ``` would become ```yaml problem_storage_globs: - /problems/ccc/nccc/*/**/ - /problems/apio/*/apio*/ - /problems/bbc/*/bbc*/ ```

Mistune v3 has been out for ~5mo by now, perhaps we should consider that instead of v2.

Superseded by #1147.

On second thought, perhaps we should either add a "characters that trigger a warning", or allow blacklists to be configurable by language, because I realized this would cause problems with...

I suspect this is because https://github.com/DMOJ/online-judge/blob/89fec363983728cfc6a7251bf958180c3f58b51f/judge/jinja2/datetime.py#L30 has the `UTC` timezone hardcoded. We could considering passing the timezone and defaulting to `UTC` if no time zone is provided.

You need to point `PROBLEM_STORAGE_ROOT` in your site's local config to a folder where the judge is configured to look.
