Add IPv6 or IPv4 to OpenVPN Settings

Please can a feature be added so when setting up an openvpn interface IPv4 or IPv6 can be specified, with the default being IPv4

Currently in 1.3 rolling when adding a hostname to an openvpn interface it defaults to IPv6 and additional openvpn options have to be specified.

The IPv4/IPV6 option should also take into account the protocol so if the tun is set to udp it uses udp4 and vice versa for tcp.
