Keep a stepped-past download from replacing the open photograph

Opening a photograph from the library starts a download and a timer that
polls for it. Every step along the roll started another, and each one put
its result on screen when it landed, so a frame stepped past earlier
could arrive last and replace the one whose name was showing. Each open
now takes a generation number; a download that lands for an older
generation is recorded in the activity list (its bytes are cached) and
goes no further.
