- ALL classes are E_NOTICE safe as far as possible.
There might be some minor things left over which will be cleaned up in
further testing
- Added declare(strict_types=1); on all pages for trying to make all
calls strict
- Added page_content sub content to edit_page, with this some inner page
content with ACL can be set, eg for use with Ajax/JS calls with backend.
Also alias can be set so the control ajax pages can back reference to
the master page content setting. Currently only one back reference is
allowed
- Note that the PAGES array has no numeric indexes, but uses the cuid as
index
