Transactions - deploy buildTransactionTimeline to remaining applications

Summary:
Ref T4712. Specifically...

- Differential
 - needed getApplicationTransactionViewObject() implemented
- Audit
 - needed getApplicationTransactionViewObject() implemented
- Repository
 - one object needed PhabricatorApplicationTransactionInterface implemented
 - setShouldTerminate(true)
- Ponder
 - BONUS BUG FIX - leaving a comment on an answer had a bad redirect URI
 - both PonderQuestion and PonderAnswer needed PhabricatorApplicationTransactionInterface implemented
 - setShouldTerminate(true) on both "history" controllers
 - left a "TODO" on buildAnswers on the question view controller, which is non-standard and should be re-written eventually
- Phortune
 - BONUS BUG FIX - fix new user "createNewAccount" code to not fatal
 - PhortuneAccount, PhortuneMerchant, and PhortuneCart needed PhabricatorApplicationTransactionInterface implemented
 - setShouldTerminate(true) on Account view, merchant view, and cart view controller
- Fund
- Legalpad
- Nuance
  - NuanceSource needed PhabricatorApplicationTransactionInterface implemented
- Releeph (this product is kind of a mess...)
  - HACKQUEST - had to manually create an arcanist project to even be able to make a "product" and get started...!
  - BONUS BUG FIX - make sure to "setName" on product edit
  - ReleephProject (should be ReleepProduct...?), ReleephBranch, and ReleepRequest needed PhabricatorApplicationTransactionInterface implemented
- Harbormaster
  - HarbormasterBuildable, HarbormasterBuild, HarbormasterBuildPlan, and HarbormasterBuildStep all needed PhabricatorApplicationTransactionInterface implemented
  - setShouldTerminate(true) all over the place

Test Plan: foreach application, viewed the timeline(s) and made sure they still rendered
