Removed unused options.  Added --bluebird-setup, --list-server, --list-authentication, --list-authorization, --set-entries, --set-mappings, --set-php-auth.  Bluebird setup mode reads config file and sets up the LDAP entries and mappings automatically.
Re-written to comply with the Drupal 7 ldap module.  Three tables are now used: ldap_servers, ldap_authorization, and variable (the "ldap_authentication_conf" variable name).
