* Update x-ui.sh with ufw port settings
It really costs time when adding rules for a large range, if for loop is used in bash. Changed it to built-in port range support in ufw.
This commit is to correct the previous one, which cannot handle port range settings correctly.
Corrected the confirmation of the deleted ports.
