Add whitelist / blacklist option in nag screen (e.g. "don't ask me again about this SSID")

[quaqo]

It would be very handy to have a whitelist / blacklist mechanism, especially for EAP networks. I understand the reason behind rejection of #17, but it would help (in my use case for example) to consciously choose respond to the nag screen "Should the network be available" with yes/no and then "never bother me again about this SSID" as an option.

My usecase is my work network to which I want to say YES everytime, and my ISP WiFi network which is present in the whole nation, to which I want to reply NO everytime, apart from a few cases where I don't have other access to the Internet.
