Removed openvpn-gui.exe restart functionality

It seems that openvpn-gui.exe loads libeay32.dll when it launches. This prevents
the OpenVPN installer from overwriting that library when it needs to, in the
"Dependencies" section. There are various workarounds, none of which are
particularly pretty, so for now the restart functionality is simply removed.
