Add RecordDataFormatter helper to simplify description template. (#829)

- Replaces extremely redundant template logic with a view helper driven by a simple, declarative configuration.
- Injects default configurations into the view helper, so that changes (adding/removing/reordering fields) can be made by customizing a factory OR by customizing templates, depending on user preferences.
- Includes a class for managing configurations, to simplify common setup tasks.
- Keeps all data retrieval logic in the record driver, but allows extremely granular display customization on a field-by-field and driver-by-driver basis using driver-specific templates.
