Auditor field in audit modal
Refactored auditor modal
Live binding for auditor field.
Don't show auditor field when no authorizations
Modals refactor #1: move owner setting to models, so Program can treat it specially
Modals refactor #2: moved Auditor management for Audit to Audit.prototype.save()
Modals refactor #3: removed dead code for old Section-Objective create-and-map modal
Merge remote-tracking branch 'origin/develop' into feature/auditor-in-edit-modal
Add `UserRole` "read" permissions for some roles

* Basically, anyone who needs to see the Auditor of an Audit should have
  this permission
Comment out 'Edit' / '+ Auditor' to avoid JS issue

* `saveAuditor` method no longer exists on the controller
Merge pull request #906 from reciprocity/feature/auditor-in-edit-modal
