The service deletes all added routes when the client process (openvpn)
exits, causing the re-instated default route to disappear.
Fix by rewriting "--redirect-gateway" to "--redirect-gateway def1" when
routes are set using interactive service.
Only the behaviour on Windows with intereactive service is affected.
Resolves Trac 778
