Partial gallery

[Zoramite]

The editor uses an examples key in the editor setting for creating screenshots and initial values when adding partials to a page.

The page builder could allow for use the examples data from the editor configuration to show a gallery of all of the partials.

This would allow for the user to easily see what partials are available across projects that use the page builder but it would also help keep the example values up to date since it will be easily seen in the gallery.
