Formbuilder customisations

This project uses a custom bc.forms app that extends Wagtail's contrib.forms

Submission auto-deletion

The FormPage model in bc.forms has a custom auto_delete field. When set to a non-zero value (zero is the default), form submissions for that form will be deleted after that many days.

This is done via a custom stale_submissions management command that's meant to be run daily.

Embedded form blocks

There's a custom EmbeddedFormBlock that allows an editor to pick a FormPage and have the form for that page be embedded inside the streamfield.

The form submission is handled by the original FormPage view, so any validation error will be displayed on the non-embedded form page. Otherwise the form's submission is recorded and a "thank you" message (configurable) is displayed (embedded).
