sbb-remote 0.12.0: named builds, per-package job results, prune

- Packages: named packages run slackrepo build, which also updates outdated
  ones; update on a named item finds only already-built packages. The
  per-row Update action is gone, Update all stays.
- A real slackrepo job reads its items' buildresults rows into the job's
  results and is failed when any item failed, aborted or was bad:
  slackrepo itself exits 0. The notification names the failed items; a
  Build results dialog lists every item with its log and Retry failed,
  reopenable from the Jobs ribbon.
- slackrepo prune: the helper lists built items whose SlackBuild is gone
  and runs slackrepo remove on them, without an Update all. stats gives
  the count; Packages gets a Prune action, the Built tile a 'to prune'
  note. Remove and prune ask for confirmation at Run it.
