/** main entry point for update wizard (called from /program/main_admin.php)
*
* This routine takes care of executing update routines for both the core
* program and modules, themes, etc. It is called automagically whenever
* the core program version in the database is different from the version
* in the file {@lnk version.php} (see also {@link main_admin()}).
*
* It can also be called manually via 'job=update'. When no specific
* task is specified, this routine shows the overview of versions for
* core, modules, themes, etc. Whenever a component is NOT up to date,
* an [Update] button is displayed. If a component IS up to date, we
* simply display the word 'OK'. This implies that when everything is up
* to date, the overview simply displays a list of OK's and the user
* is 'free to go'.
*
* The actual updates for modules, themes, etc. is done via the various
* subsystems themselves, e.g. by calling htmlpage_upgrade() in the file
* /program/modules/htmlpage/htmlpage_install.php. The updates for the
* core program are actually performed from this file right here, see
* {@link update_core_2010120800()} below for an example.
*
* Note that we give a core update high priority: if the core
* is not up to date, nothing will work, except updating the core.
*
* @param object &$output collects the html output
* @return void results are returned as output in $output
