Enhancements

Fix not processing quotes in ws-headers in Surge VMess configurations.
Fix when default_url is set and insert_url is not set in YAML configuration and access /sub without url argument, the nodes in default_url will be added twice.
Add /version interface to compatible with some front-end.
