Make PonderQuestionEditor use ApplicationTransactions

Summary:
Ref T3373. Make PonderQuestions editable and use transactions.

This temporarily disables some stuff:

  - email;
  - feed;
  - comments;
  - voting.

I'll restore those in followups and wait to land this until they're at least mostly back online.

The transactions themselves also need more string/color/icon work.

Test Plan: Created and edited questions. Viewed transactions.

Make adding an answer to a Ponder question a QuestionTransaction operation

Summary: Ref T3578. This is currently handled in a weird way in the Answer transaction. Instead, make it a Question transaction so, e.g., viewing Question transaction history shows who added answers and when.

Test Plan: Added answers to questions in Ponder.

Require answers' authors to be unique in Ponder

Summary: Ref T3578. I forget if this was an explicit decision or not, but we currently let the same user answer questions multiple times. I think this probably causes more confusion than it provides freedom. In conjunction with other UI issues (commenting being weird, notably), we're seeing some use of answers to comment, which is undesirable. Require each answer's author to be unique. Merge existing nonunique authors' answers.

Restore comments on Ponder answers

Summary:
Ref T3373. This is still pretty messy:

  - The JS bugs out a bit with multiple primary object PHIDs on a single page. I'll fix this in a followup.
  - The comment form itself is enormous, I'll restore some show/hide stuff in a followup.

Test Plan: Added answer comments in Ponder.

Fix bug when multiple comment forms appear on a single page

Summary:
Ref T3373. The submit listener doesn't properly scope the form it listens to right now, so several forms on the page mean that comments post to one of them more or less at random.

Scope it properly by telling it which object PHID it is associated with.

Test Plan: Made Question comments, saw comments Ajax in on the question itself rather than on an arbitrary answer.
