prevent renaming of special groups

when sub=to and we remove a contact, don't show the check button "allow other part to view my status" as he is already not interested in it. This result in removing contacts with sub=none, ask=none

revert buttons in notif-daemon popups. notif-daemon new release will fix position bug reported as attach in #1537

when sub = 'to' and we remove contact (but allow other side to see our status) completely remove contact

re-introduce button in notification in order to see it fully on screen. I just took Andrew's code from #1388 patch04. Fixes #1537

closed the connection

we have to remove group from contact instances before removing them from roster so that gajim.groups in cleaned up. Fixes #1778

when we edit groups of a contact, groups of all brothers are also updated to they are sync. Fixes #1770
