Update Form Layouts

Summary:
This attempts some consistency in form layouts. Notably, they all now contain headers and are 16px off the sides and tops of pages. Also updated dialogs to the same look and feel. I think I got 98% of forms with this pass, but it's likely I missed some buried somewhere.

TODO: will take another pass as consolidating these colors and new gradients in another diff.

Test Plan: Played in my sandbox all week. Please play with it too and let me know how they feel.

Generate PHP function documentation in Diviner

Summary:
Ref T988. Various improvements:

  - Generate function documentation, mostly correctly.
  - Raise some warnings about bad documentation.
  - Allow `.book` files to exclude paths from generation.
  - Add a book for technical docs.
  - Exclude "ghosts" from common queries (atoms which used to exist, but no longer do, but which we want to keep the PHIDs around for in case they come back later).

This is a bit rough still, but puts us much closer to being able to get rid of the old Diviner.

Test Plan: See screenshots.

Fix Phriction feed stories text rendering

Summary: Fixes T3763. All this junk needs some actual fixing at some point, but stop it from fataling.

Test Plan: Used `feed.query` with `view=text`. Before this patch, Phriction stories fataled. Now they render reasonably.
