Mod/Admin option to "speak officially"

[Nutomic]

Reddit has a nice feature where it allows admins or mods to select explicitly if they are "speaking officially" in a comment. In that case, the comment gets highlighted. This is very nice because it avoids misinterpreting personal statements as official communication, or vice versa.

I like this. Reddit calls it "distinguish", but we could probably come up with something clearer.
