Edit any note and its images from the admin page

Every note gets an Edit form built from its note type's schema: image
fields show a thumbnail with a pick from the vault or an upload, link
fields offer note names, and lists of rows can be added to, removed and
reordered. A new Site pages view lists each page of the site with its
text and images and the notes that fill it. Image and link fields now
carry a JSON Schema format so a form knows to offer a picker.
