Mambo modifications

Mambo has now been modified to work with options similar to limbo
like external authorization, auto login and auto user registration.

The names of the variables respectively are
1) $mosConfig_ect_auth

2) $mosConfig_auto_login

3) $mosConfig_auto_user_registration

The files that have been modified for this to work are includes/mambo.php, index.php and modules/mod_login.php.

However, currently the entire mambo directory is being protected by shibboleth, and the anonymous user scenario is still not in place, which i am currently working on.
