Publish create object stories into Asana sort of, but not really

Summary: Ref T2852. Current code works fine, but although we want to drop creation stories, we really only want to drop the story text, not the other effects of the creation story. Also generalize this mechanism so we don't have Asana-specific code in the publishers.

Test Plan: Used `bin/feed republish` to publish creation and non-creation stories. Verified creation story published no text.

Pholio - finish off history view

Summary:
...bsasically add a "view mode" and play with that throughout the stack. Differences are...

 - normal mode has comments; history mode does not
 - normal mode has inline comments; history mode does not
 - page uris are correct with respect to either mode

 ...and that's about it. I played around (wasted too much time) trying to make this cuter. I think just jamming this mode in here is the easiest / cleanest thing at the end. Feel free to tell me otherwise!

This largely gets even better via T3612. However, this fixes T3572.

Test Plan: played around with a mock with some history. noted correct uris on images. noted no errors in js console.

Restore setting "disabled" on user handles of disabled users

Summary:
Fixes T3666. D6585 updated the User handles, but accidentally dropped this unusual property.

We should get rid of this -- it doesn't really make any sense on Handles -- but restore the previous beahvior to fix T3666 until we can nuke it.

Test Plan: Clicked some pages? (Actually testing this properly is a bit of a pain and I am super lazy.)
