Merge profile "About" into main profile and simplify some custom field stuff

Summary:
Ref T1703. Drive "user since" with a custom field and make the other fields render into a property list.

Users can make their profiles a little more personal/obnoxious now.

Also delete a bunch of code.

Summary: I'll probably move "away" to a custom field, but this is technically broken right now.

Use ActionListView for all profile actions

Summary:
This leaves the space between the properties and the blurb looking a bit empty, but there will be more stuff there soon (status, VCS names, email, phone/fax numbers, etc., and custom user fields).

I removed "view lint messages" since I'm pretty sure no one has ever clicked it. I think providing better search (e.g, T2625) to that UI in Diffusion is a preferable approach.

Send audit emails to more users

Summary:
Audit has some weird rules about who gets email. Make them less weird:

  - When a user does "Add Auditors", email the auditors.
  - When a commit is commented on, email anyone in "concern" or "audit required" states.

@staticshock, my claim that I can't reproduce was crazy, I just have weird test data and read it wrong.

Test Plan: Added a user to an audit and verified they got an email.

Legalpad - add signature page

Summary: Fixes T3481. Sort of - this thing be very ugly. Also it assumes that you'll "always" want to sign terms. I was thinking in a future diff that should be optional as well as configurable, though it was unclear to me if either was worth pursuing...  Generally very hideous as the three main elements (PHUIDocument, AphrontErrorView, and AphrontForm with an AphrontFormInset) have never really played together before.

Test Plan: agreed to some test terms. noted UI displayed nicely. reloaded and noted UI told me I had signed it already. Went to different terms and filled them out wrong and got sensical errors.
