When a user accepts a revision, accept for all projects the user has authority over

Summary: Ref T1279. If you accept a revision, also accept on behalf of all the projects you have authority to accept for.

Test Plan:
  - Accepted a revision which I was a reviewer on, saw my own status and an authority project's status change to "Accepted".
  - Accepted a revision which I was not a reviewer on, saw my own status be added (as "Accepted") and the project's status update.

Also, see screenshot.
