Xenforo 2.1.x Vietnamese Translation xenforo 2 2.1.9

I made this Vietnamese translation on my own to use on my forum . I did it long time ago and improved it day by day to facilitate my forum's need. It probably contains some buggy phrases, hope you will give me constructive feedbacks so that I have the motivation to do it better. Thank you and best regards.
