[PATCH] Windows: send local DNS hostname during connection

[Alexey Smirnov]

Windows client do not send local computer name and the server assumes
default "localhost" if not forced by command line option. This
prevents server scripts to run that somehow depend on the DNS name of
the connected system. (like updating DNS records when a new VPN client
connects)
This is my first patch/email so I can easily make something wrong.
