Assemble an issue or change from the indexed rows

The detail pages can read the same rows the lists do, as long as the
refresh runs first (it does) and the assembled record is exactly what the
branch says. Add Store.Issue and Store.Request, which put one entity back
together from its row, its comments, and — for a change — its closes and
approvals.

Two orderings had to be stored rather than inferred:

- request_closes keeps the file's position, because the branch lists the
  issues a change closes in the order the author wrote them, not in id
  order.
- comments and approvals are read in the same id/principal order git's
  path listing gives, so a rebuilt thread matches the one read from git.

The tests compare both readers field by field (reflect.DeepEqual) on an
issue with labels, assignees, a reply and a comment, and on a change with
two closes, an anchored comment and an approval. The schema version is
bumped so existing rows are rebuilt with the new column.
