Clemens Schwaighofer 46554e6965 Update to make all class E_NOTICE safe, add page_content
- 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

* AUTHOR: Clemens Schwaighofer
* CREATED: 2011/2/8
* DESCRIPTION: pre function to collect all non critical errors into a log file if possible
* include this file at the very beginning of the script to get the notices, strict, etc messages.
* error etc will still be written to the log/display
*********************************************************************/

// RETURN: true, so cought errors do not get processed by the PHP error engine
// DESC: will catch any error except E_ERROR and try to write them to the log file in log/php_error-<DAY>.llog
// if this fails, it will print the data to the window via echo
