Kick/ban notify
When I kick/ban someone, he should recive message about this action (it's specified in muc JEP I belive). Current gajim does not sopport this so people kicked/baned from muc don;t know they where kicked. They don't know becouse of lack of any notify about such action. They also can send to chat window without any error message. Would be nice if:
- Input box will be grayed (not allowing to input)
- Message about kick/ban (reason) should be displayed somewhere in visible place (probably this grayed input)
