Summary: Ref T9132. Fixes T5031. This approximately implements the plan described in T5031#67988: When we recieve a preview request, don't write a draft if the form is from a version of the object before the last update the viewer made. This should fix the race-related (?) zombie draft comments that sometimes show up. I just added a new object for this stuff to make it easier to do stacked actions (or whatever we end up with) a little later, since I needed to do some schema adjustments anyway. Test Plan: - Typed some text. - Reloaded page. - Draft stayed there. - Tried real hard to get it to ghost by submitting stuff in multiple windows and typing a lot and couldn't, although I didn't bother specifically narrowing down the race condition.
