Scene Manager: request publishes missing on this site

- Request (globe) on casting rows and loaded assets whose latest publish
  is not on this site, and Request Missing for all of them, through the
  new wtdcmds command wtd_request_revisions. Requested publishes show
  "requested, waiting for the download".
- The version picker requests a version that is not on this site.
- A 404 explains that the session is gone or wtdcmds is too old.
- Fake server: car (vehicles) with a publish not on this site,
  wtd_request_revisions and /_test/download; 45 checks.
- Tested live: car_paul modeling.blend v001 -> Requested.
