Keep a feed out of Signals, and a feed's settings in named parts (#289, #290)

hide_from_signals on a subscription, on an OPML or creator covering every
show in it, as hide_from_all does for All Subscriptions: the judge does
not put its items to Jev, and each Signal's list and counts leave them
out. shown_in() is the one SQL rule for both.

The settings dialog had grown one captioned setting at a time into a
single column, one part boxed and the rest not. It is in named parts now,
the name in a column beside the controls and above them on a phone, ruled
apart; All Subscriptions and Signals carry the sidebar's icons. The
address, the same for everyone, moves to the foot.
