Release 1.3

versionCode 4. public_html/ changed, so the service worker cache goes to
bgclock-v19 — without it an installed web user would keep serving the old page
from cache indefinitely.

The five store screenshots are untouched: the ring only exists while a finger
is on the button, and none of them shows that.
