Broadcast should only go to person who has broadcaster as contact

While reviewing whatsapp, I found this restriction on broadcast feature. The broadcast can only go to those contacts who have added the broadcaster to their address book. This would save from spamming. I would think how we can do this work. We might do server side work for this.

@sumairasaeed we will do design discussion on this task before we carry on this.

Yes ok.

After thinking on design I found the easiest way to put this restriction and it would be done on server side and not client side. Server will check if recipient in broadcast list has broadcaster in contact or not. Thus server will itself reject message for that person.

We would do little change on server side where address book is synced for first time. In this, We should not make a two way friendship if contact in address book of a user is found on cloudkibo, we should make only one way friendsihp.

I will do the server side work and track it in this task. Then we can close it.

I have completed the server side work in this and pushed the code. Please reinstall the application in order for this to take effect.
