CC-2166: Packaging Improvements. Moved the Zend app into airtime_mvc. It is now installed to /var/www/airtime. Storage is now set to /srv/airtime/stor. Utils are now installed to /usr/lib/airtime/utils/. Added install/airtime-dircheck.php as a simple test to see if everything is install/uninstalled correctly.
