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:
Precursor to building this out to solve T343. This is similar to the Maniphest
fields we landed recently, although I think they're dissimilar enough that it
isn't worth going crazy trying to make them share code, at least for now.
This doesn't really do anything yet, just adds a storage object and a couple of
selector/field indirection classes.
Test Plan: Ran SQL upgrade script, created an aux field.
