D1868: evolution: make reporting of new unstable changesets optional

REVISION SUMMARY
  This makes it possible to turn off the reporting of unstable
  changesets (e.g. "1 new orphan changesets"), just in case it's too
  slow for some users. Anyone who's been using the evolve extension has
  already been accepting the cost of the reporting, so this is just for
  the few users who have turned on obsmarkers but not been using the
  evolve extension (as I believe Facebook has).
