Feature Request: Disable Preview on Markdown field

[bkuhl]

The Ask

It would be awesome to be able to ->disablePreview() on a Markdown field, since it doesn't work in all scenarios.

Why

I'm using a Markdown field within an action. The field is used to require a "Reason" for the action being executed and the field isn't actually attached to my resource. As a result, when the markdown field's "Preview" option is used, the ajax request (which is sent to https://my-site.com/nova-api/[RESOURCE]/field/[FIELD]/preview?editing=true&editMode=create) ends up with a 404 error. I understand it relies on this resource because action fields associated with a resource need to be scoped to the resource the action is being performed on, which is why I think simply disabling the preview might be the better option.
