Improved error msg if checkbox "Editable for Admins Only " set
If checkbox "Editable for Admins Only" is set on a page, the records inside can be opened by an editor and there is the save btn but it will lead to an error "...without permission. Or non-existing page."
- drop save button
- add flash message in sys folder + single record to inform user
- change all fields to readonly just like it would be for ctrl>readOnly = 1
No data to display
