* include includes/functions.php so that we have access to all it's contents
* add a beforeDelete function which deletes the files. Add other needed functions like Path() LinkPath() etc.
* add require_once for Storage and functions because we use them in Event
* Now that ZM has namespaces use the ZM Event class to do the heavy lifting of delete
* Don't need functions in AppController anymore
* Introduce ZM_COOKIE_LIFETIME which sets the life of the SESSION cookie, instead of using what is in php.ini
* Use zm specific session functions, which are now located in includes/session.php. Be more agressive about clearing session on logout.
* Move session code to includes/session.php
* remove duplicate line
* Move is_session_open to session.php. Move code to clear a session into session.php
* improve debug line when there is a problem updating config entry
* split description into description and help text for COOKIE_LIFETIME
* Remove redirect on line. We do it in javascript on postlogin view so that we can say logging in before switching to console
* If there is a username in the session, then we are logged in, but we need to load the user object from the db. We can't just trust it from the session. The user may have been deleted and having that data in the session can be a security risk. So load the user object on every request.
* Use session_regenerate_id instead of our broken code to do the same
* Move auth code to includes/auth.php
* add autocomplete tags to username and password inputs
* Don't redirect to login if we are already viewing login. Put auth before including skin includes
* need to include session.php in auth.php
