fix logic in handle_event_msg so messages from lower resource doesn't behaves incorrectly. Fixes #1785

unsensitive most menu items in context menus of contact / group / transport / account when account is offline and prevent renaming of contact / group. See #1754

if we have status message for contact that signs in/out and we have such notifications, include the status message information in those windows

it unwise to include the "inconsistent use of tabs and spaces in indentation" warning.
Filtering stderr works, but may also filter out useful info.

* Add option 'dont_ack_s10n' to prevent the infinite loop with jabberd2 subscription acknowledgements.

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
