WebGUI protocol HTTP / HTTPS per Interface

[NOYB]

WebGUI protocol: HTTP / HTTPS

Please add support for assigning WebGUI protocol on a per interface basis.  e.g. LAN HTTP, WAN HTTPS, other/optional, etc.

I'm not sure how feasible this would be, but it may be possible with multiple instances of lighttpd. There is an HTTP->HTTPS redirect that happens on 2.0 now since HTTPS is the default.
