Look a group's title up once, not once per feed in it (#159)

Browse Source 
subscriptions() names each feed derived from an OPML or a Patreon creator after its group when the
group has no folder, and asked feed_summary, three queries, for the group's title once for every
feed in it: the same title each time. Production's 32 Glass Cannon Network shows made that about 96
queries each time it ran, which is every feed list, every live update the page receives, every scan
and every wait between scans. It now asks once a group per call.

### Fixed
- The feed list, and each live update of it, no longer asks the database for a group's title once for every feed in the group.
- An episode that came as a torrent of several files plays its largest file, and can be deleted, by hand or to free space, instead of staying on disk for good.
- Removing an account takes the feeds only that person read off the server, as unsubscribing does, instead of leaving them downloading every new episode for no one.
- Freeing disk space counts only the people who subscribe to a feed: an episode is no longer taken as heard by everyone because someone who has since unsubscribed heard it, and their pins no longer keep files for good.
