Changesets Ranking

[Piszmog]

When a user creates a large number of changesets, interesting changesets should be displayed sooner.

TODO

• Define what interesting is
  • Ideas: Age of repo, date of last commit, # of lines of changes

Done

• Implement a ranking system for changesets

See also the now closed #43397 for more detail on things we could do with outliers.
