Upgraded Zend Framework to version 1.12.9
Removed unused cron job, and minor changes to the most-active-communities.php job.
Removed weird global declaration for $translate.
Visual updates to the Communities index page, including refined community search. Update to the search_description() function in functions.inc.php.
Updated the "Previous" & "Next" links to use the Bootstrap style pager.
Removed breadcrumbs from non-admin side as I'm not sure they're needed. Also used the bootstrap style breadcrumbs instead.
