* d) main application area
* e) footer
* It replaces several methods in the common class and the diverse templates.
*
* Existing apps either set $GLOBALS['egw_info']['flags']['noheader'] and call common::egw_header() and
* (if $GLOBALS['egw_info']['flags']['nonavbar'] is true) parse_navbar() or it's done by the header.inc.php include.
* The app's hook_sidebox then calls the public function display_sidebox().
* And the app calls common::egw_footer().
*
* This are the authors (and their copyrights) of the original egw_header, egw_footer methods of the common class:
