[PATCH 4/6] Improved vpnc-script.js

[Ľubomír Carik]

From: Zhenyu Wu <Adam5Wu at users.noreply.github.com>

2. Added REDIRECT_GATEWAY_METHOD = -1 mode, which leaves default route intact, but do all other necessary route setup. This mode can be used by advanced users who already have the persistent route set up. For example, only certain IP/subnet will to through VPN, while all other traffic still go through native interface (improves latency for, i.e. Google search)
