Add a new endpoint that will mark a particular revision as patrolled:
- PATCH /api/tools/{tool_name}/revisions/{id}/patrolled/
All edits should start life in an unpatrolled state. Users with the Patrollers right should be able to toggle this to a patrolled state after review of the edit. This action should also emit an audit log event showing who marked the edit as patrolled. Revision output from the API should report the current patrolled state.
