Simplify Project status field

Summary:
This was a sort of speculative feature added by a contributor some time ago and
just serves as a label; for now, simplify it into "active" and "archived" and
remove "archived" projects from the "active" list.

  - Fix a bug where we'd publish a "renamed from X to X" transaction that had no
effect.
  - Publish stories about status changes.
  - Remove the "edit affiliation" controller, which has no links in the UI
(effectively replaced by join/leave links).
  - Add query/conduit support.

Test Plan: Edited the status of several projects.
