Move audit to application transactions

Summary:
Fixes T4896, T6293.

Do most of the work in the editor, but pull the raw patch in the daemon and set that on the editor. This is somewhat of a pre-optimization but it was easy enough to do and makes sense to me.

Test Plan:
made a commit and saw it get parsed.
made a commit with "Auditors: foo" field and saw audit made for foo
turned on inline patch and attach patch and saw the patches
