*   Attachables now can override default attachment missing template.

    When rendering Action Text attachments where the underlying attachable model has
    been removed, a fallback template is used. You now can override this template on
    a per-model basis. For example, you could render a placeholder image for a file
    attachment or the text "Deleted User" for a User attachment.

    Streams) now use `Rails.application.default_url_options` and
    `Rails.application.config.force_ssl` instead of `http://example.org`.

*   Support `strict_loading:` option for `has_rich_text` declaration
