Add site setting to default search results sort by latest post instead of relevance

[JammyDodger]

I’ve just closed a couple of similar feature requests to focus the discussion here, but this one seemed relevant to cross-post:

I think adding a site setting that allows you to pick default site sort order would be useful in some cases:

I agree with @codinghorror 100% that our default of “Relevance” is correct, but can see cases where there is a very strong preference for latest (either post or topic).

I am not keen on making this a strong per user setting quite yet though. @codinghorror should we slot adding this site setting, or wait on this for a bit?
