Remove button "Pause VPN" from notification

After the update of ics-openvpn there's an notification that shows the current status of the vpn (connected location if provider specified that, current up- and download rate, overall up- and download). Additionally there are two buttons: Disconnect and "Pause VPN". The bitmask client for linux doesn't have an option to pause the vpn. Moreover the pause functionality is buggy. That's why the button should be removed (at least for now)
