Various updates

Various functions have been changed to update the CHANGE_DATE field for
reporting purposes.  Also, the UserList class (and it's unit test class)
were obsolete and have been removed.  Lastly, the SessionManager class
function forceAuthentication() has been temporarily commented out since
the MobileDetect class has been relocated.  Lastly, the login, logout,
and index files have updated references to the MobileDetect class.
