[FEATURE] Whitelist addresses for individual apps

[sjau]

Hi really like AFWall+. It's easy to use and it opened my eyes to see how many apps that want internet access without any real need for it.

However I've been thinking if this is possible: Restrict apps to certain addresses that they can reach but not allow them to connect to others.

E.g. a email app should only needs to contact your pop/imap/exchange/active sync servers. There's no need for an email app to connect to other addresses.

So is it possible to not just dis/allow network access but also limit it to specific addresses?
