Remove in-list spinner + add monitored-repos setting; bump to 2.3

- Remove the in-list loading wheel overlay; the landing page just shows the
  cached list or the 'No open PRs' screen.
- Add a 'Monitored repos' setting (Settings > Inbox) that limits the inbox to
  specific repos, cutting the number of API calls dramatically. Empty =
  monitor all accessible repos. Bump to 2.3.
