This change will add default icons for Builtin Space Templates.

… (#2527)

Prior to this change, when adding a page template, the images attached
to it are not viewable by External users. This is due to the fact that
the access permission of attached image is computed switch page being
edited, or if of type page template to current page (layout-editor).
This change will fix two bugs:
- Give access to layout-editor page to anyone to let the ACL made by
page permissions instead (by the Space Layout permissions if the page is
added in a space)
- Make the attached image to a fictive page (not really instanciated
yet), accessible to all users since the page can be used in any
site/space.

This change will allow Space Managers to edit their public sites pages by changing the sites layout management button access permissions.
