Summary: Depends on D798. Extends custom fields and makes the vaguely useful:
they can appear on the edit and view interfaces. This does not integrate them
with commit messages yet; that's more complicated but I plan to do it shortly.
Test Plan: Implemented a custom field per P123, it correctly appears on the edit
interface, persists, validates, and shows up when viewing the revision.

Summary: The field hints on this interface don't behave correctly. Particularly, when you add yourself as a reviewer you aren't pointed at the issue.
Test Plan: Edited a revision and tried to save invalid changes, including self-reviewership.
