Load the feed list in five queries, not six per feed (#94)

Browse Source 
GET /api/feeds called feed_summary, http_state, blocklist and unread_count for every feed:
about 950 round trips to Postgres for 160 feeds, 320 ms on every page load. Db::feed_list asks
for the feed rows, entry counts, download counts, the person's unread counts and block lists
once each, and the handler reads from that.

### Fixed
- The feed list loads several times faster: it was asking the database six questions per feed.
- Artwork a feed offers only over plain http shows on the https site too.
- A failing feed is easy to spot in any theme: a mark on its artwork, what is wrong in place of
its counts, and its artwork greyed out once it has failed for a day.
