Added ability to easily put a site in maintenance mode by changing the name of maintenance_off.php to maintenance.php. Reasoning behind using this method is a bash script for updating Ushahidi can be set up to rename the file at the beginning and the end of the update to automatically put the site in maintenance mode and then take it out.
