Fixed bug in cron.php which was causing it to not run correctly.

Added IP blocking and extra logging to cron.php, so we can see if a bot is repeatedly trying
to access cron.php (and potentially block their IP).

Minor tweaks to stop warnings/notices in PHP 8.

Modified the installation script so that the settings.php file stores less information about the database connection in the GLOBALS array.

Modification also makes it so if the user changes db connection information in settings.php (eg, the db_host), it will respond accordingly. Previously the db_host was stored in a session variable, causing the user to need to log out to see changes.
