Subject: [PATCH] Moderator rule: nodvd (exempt from dark video detector)

Some users had reported the dark video detector errors out on their
camera, reading a solid black image and average color of 0 despite their
camera actually being bright and colorful.

This case seems rare, but the nodvd moderation rule can lift the feature
for specific affected users while keeping it in place for everyone else.
