New Thing: Shifting Order on the Homepage

I want to do more with the homepage in general. This is a start.

Aside from supplemental/specialized combo feeds, I'm going to start re-ordering the most recently-posted show in the top left corner of "the grid" (which you can see in effect on the front page now).

This keeps things moving and fresh, where they'd otherwise be static.

We're adding a People/About page soon, since there are something like a dozen people hosting shows in total, and I prefer that to the notion of a page that only has a summary of the network's history.
