Always exit Xvnc whenever the user exits the window manager, and provide a -fg switch to allow Xvnc to run in the foreground (necessary for some grid computing environments)

+This version of vncserver will always launch Xvnc in such a way that, when the
+user exits the window manager in their VNC session, Xvnc will terminate.
+Specifying this option will additionally make Xvnc run as a foreground process,
+which means that it can be aborted with CTRL-C.  This may be necessary when
+launching TigerVNC from within certain grid computing environments.
