Home page: a screenshot for Signals in place of the drawing (#254)

The drawn list's made-up titles read badly. The screenshot is a Signal
called Space on a scratch iPX on eight public feeds, with a stand-in
for Jev matching the Signal's words in titles, in Glass as the other
shots are.

         <p>Make a Signal with the words to listen for, and a sentence saying what you mean if the words are not enough. iPX reads everything your podcasts and blogs bring in and keeps what is about it in a list of its own, so one subject is in one place however many feeds it turns up in. Signals need a key of your own from <a href="https://typesafe.ai">typesafe.ai</a>.</p>
