Prompt the Windows user to run the server as admin

Added #142.

If Windows OS then it won't show the access denied exception, but
instead, will debug a message, and prompt the user to run to server as
an administrator.

Also added a name to the console window. Which is DMPServer +
PROGRAM_VERSION + ", protocol " + PROTOCOL_VERSION
