v 0.7.6-internal

- Added `access_key` variable in Config, this used to access restrited plugins when multiuser plugin is enabled. When MultiUserPlugin is enabled we cannot access some pages like /Stats, this key will remove such restriction with access key.
- Added `last_connection_id_current_version` to ConnectionServer, helpful to estimate no of connection from current client version.
- Added current version:  connections to /Stats page. see the previous point.
