* bin/pandora_server: Now uses $Config{"enterprise"} to know if
enterprise is loaded, and don't try to call enterprise_hook if is not.
I experience a high rate of inventory-enterprise hook errors in log.
* SNMPServer.pm: Dont call snmp_get_trap2agent enterprise_hook if
not enterprise loaded.
* DataServer.pm: Dont call process_inventory_data if not
enterprise loaded.
* util/pandora_backup.sh: New command line backup and restore tool.
