change community page to show simple listing for < THRESHOLD

Reticketing from #1316. We basically want just the "Newest Participants" listing, but not titled as such and maybe a simpler presentation.

I'm pretty sure we've agreed that below the current three columns, there'd be a a full-width area for all users, with a button to load the next bunch of them. It seems like that would exist no matter the number of people in the community, so perhaps for small communities we could update the current "new members" column so it's a full-width section, but only one row tall. Something like:

I don't remember agreeing to that. :-(

My understanding was that the "more" button on #970 would effectively turn the existing three-column layout into a listing of all users. No?

We also have to think about what this page will do on mobile.

I think we should implement this by only showing the "New Participants" listing below NMEMBERS_THRESHOLD. That is simple and effective and is a small change to make.

(The challenge of the "more" button on mobile properly belongs to #970.)

Addressed in #1910.

I just dropped NMEMBERS_THRESHOLD to 0. I realized that #963 actually helps us here, in that it lessens the chance of inferring who gives to whom. Any viable community should fairly rapidly surpass the stage where inference is a problem. And it's not a huge problem, anyway, because it does take a little work and we're not super hardline about this (we expect people to tell other people on Twitter when they're giving to them, e.g.).
