* CC-6088: Smart Block form needs to have a form layout
* CC-6089: Editor view name fields must be made <input> fields
* CC-6103: Cannot create webstreams
* Reworked a big chunk of the smart block editor flow to send only the
playlist contents back rather than the entire HTML fragment for the
editor.
* Keep more of the playlist/smartblock editor view persistent across
saves, generates, and shuffles.
