Make DeviceStandby control network interface link status on Windows.

Browse source 
Besides controlling when tinc-up and tinc-down get called, this commit makes
DeviceStandby control when the virtual network interface "cable" is "plugged"
on Windows. This is more user-friendly as the status of the tinc network can
be seen just by looking at the state of the network interface, and it makes
Windows behave better when isolated.
